...programming, polymorphism (from the Greek meaning "having multiple forms") is the characteristic of being able to assign a different meaning or usage to something in different contexts - specifically, to allow an entity such as a variable, a function, or an object to have more than one form. There are several different kinds of polymorphism. 1) A variable with a given name may be allowed to have different forms and the program can determine which form of the variable to use at the time of execution. For example, a variable named USERID may be capable of being either an integer (whole number) or a string of characters (perhaps because the programmer wants to allow a user to enter a user ID as either an employee number - an integer - or with a name - a string of characters). By giving the program a way to distinguish which form is being 2) A named function can also vary depending on the parameters it is given. For example, if given a variable that is an integer, the function chosen would be to seek a match against a list of employee numbers; if the variable were a string, it would seek a match against a list of names. In either case, both functions would be known in the program by the same name. This type of polymorphism is sometimes known as overloading. 3) Polymorphism can mean, as in the ML language, a data type of "any," such that when specified for a list, a list containing any data types can be processed by a function. (For example, if a function simply determines the length...

...Prokaryotes and Eukaryotes are somewhat similar in the chemical aspect. They both contain nucleic acids, proteins, lipids, and carbohydrates. They both use the same kind of chemical reactions to metabolize food, build proteins, and store energy. It’s the absence of organelles and the structure of cell walls and membranes that differentiate a prokaryote and a eukaryote. Prokaryote comes from the Greek word meaning pre nucleus. The DNA is not enclosed within a membrane has a singular circularly arranged chromosome. Prokaryotes DNA does not contain histones but does have other proteins. They divide by binary fission, this is when the DNA is copied and the cell divides into two cells. The prokaryote does not contain a membrane-enclosed organelle. The prokaryote cell wall contains the complex...

...10〗^(-9) m.) In contrast, UV waves are shorter, which are less than 400 nm. Ultraviolet light is also categorized as: UV-A (400-320 nm), UV-B (320-290 nm), and UV-C (290-180 nm). Light travels in waves but in the form of particles called photons. Short wavelengths of light generate more energy because of the lack of distance that photons have to travel to, to collide with each other; and since ultraviolet light waves are shorter than any of visible light, it is more energetic (Ultraviolet Radiation). As a result of its high energy, UV light can disrupt chemical bonds that make up the cells of living organisms, especially chemicals in DNA. DNA, which carries information for growth and function, is conventionally damaged by the daily exposure to UV light. DNA-coded proteins in our cell control cell growth and capacity. UV light disruption to DNA can cause a cell to become cancerous or to...

...polymerases behave with each other and how mutations amongst polymerases and DNA affect the activity of polymerases. After conducting studies, the function of the three different types of polymerases were thought to be determined. Pol α was believed to start the process of making new DNA. Pol δ was determined to elongate Okazaki fragments until the replication is completed. Pol ε was not used in this model for DNA replication. However, in further evaluation of polymerase activity, Pol ε was...

...Linguistic and Archaeology anthropology all four fields have a very diverse approach to the study of humans. For example Cultural anthropologist are more focused on things like social and religious beliefs within the human species. While Biological (Physical) anthropologist are interested in the evolution of humans. Linguistic anthropologist study languages within the human’s species. And lastly Archaeology anthologists studies humans by fossil remains. While even though all four sub fields study the human with different approaches they all still use a scientific method in their researches to study human kind. I’m a primate. You’re a primate everyone reading this is a primate. We hear humans are primates, but what does that mean that humans are ancestors to apes? No not exactly it just means that we share similar traits with primates such as apes and chimpanzees. According to the Smithsonian magazine “humans share more DNA with lemurs, monkeys, and apes than they do with any other mammals.” Carl Linnaeus was the first to classify humans with monkeys and apes in his 18th century taxonomic system. So now that we know that we similar apes what traits do we really share. Well first vision humans an apes can both see color. The ability to stand upright while humans always walk on 2 legs so can apes. Both humans an apes share the same diet we are both omnivorous meaning we eat both plants and meat. Communication and language is another trait that we share and also sociability both...

...Stein June 24th 2012 Fingerprinting DNA fingerprinting, also called DNA profiling, applies a test to determine the unique DNA sequence that each person has for the purpose of identification. In the 1930s, police detectives found each person has different patterns on the tips of the fingers, and these fingerprints became the standard for identification. However, the finger patterns can be altered by surgery or other means. DNA within living cells is difficult to alter. Sir Alec Jeffreys at the University of Leicester invented genetic printing in the mid 1980s. The DNA profile is similar to a fingerprint, existing only for that person. Jeffreys coined the term DNA fingerprint and envisioned its powerful use. A single hair, a drop of blood, semen, or other body fluid can reveal the identity of a person. DNA fingerprinting is used for identifying people, studying populations, and forensic investigations. It is in the area of forensics and crime detection that DNA use is the most promising-- as well as the most controversial. The technology of DNA fingerprinting is based on a single assumption that no two people have the same DNA. The 3-billion-base sequence is made of four biochemical blocks or nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The base pairs produce more combinations or variations than there are humans. In DNA fingerprinting, scientists focus on a segment where sequences vary a great deal from...

...How DNA has changed the Criminal Justice System Dorothy Harris Professor Sean Kelley Information Technology in Criminal Justice November 9, 2011 How DNA has changed 1 The technology has changed many aspects of the criminal justice system, and the use of DNA evidence represents one of the best examples on how technology has change the criminal justice system. The use of DNA has changed by allowing other materials beside blood to be used as identification. The DNA technology is behind what it takes in solving criminal cases, and the meaning between guilty and not guilty or life or death. There are various ways that the criminal justice system uses DNA technology. DNA has been used to analyze and prove innocence or guilty of suspects of crimes with great accuracy. DNA is part of everyday life. IT is the heredity material in humans abs almost all other organisms. In 1994, the DNA Identification Act established a national DNA database, run by the FBI, called CODIS (Combined DNA Identification System), which links all states. While the creation of DNA databases often can be defended case by case, the development of this technology serves an end in itself apart from any particular application. It provides an inescapable means of identification, categorization, and profiling, and it does so with a type of information that is revelatory...

...GENOMIC TANDEM REPEATS AND DNA FINGERPRINTING In the human genome, sequences of repeated nucleotides are repeated in tandem hundreds of times at dozens of different regions throughout ones genome. DNA profiling uses these numerous repetitive sequences as a method of identifying individuals. These repetitive sequences, called variable number tandem repeats (or VNTRs) and short tandem repeats (STRs) are highly variable and thus form excellent tools for genetic individualization. CLASSES OF GENOMIC TANDEM REPEATS An STR simply put is a short stretch of repeated units of DNA bases, usually comprising of 3-5 base pair segments that are repeated in long strings of DNA. As a result of their length, tiny samples can be easily analysed as they are amenable to amplification by...

...different methods in order to take what they want from unsuspecting members of the public. There are multiple reasons why criminals commit crime via the Internet, however the most common crimes are the theft of money, the theft of identities or information and finally the damaging of others computers via methods such as viruses. Out of all of the crimes committed over the internet the theft of money from others is the largest due to a number of reasons, however the main reason is that its probably the easiest to do as more and more people are buying and selling products over the internet with the use of credit or debit cards. Criminals are easily able to access these details if members of the public aren’t careful with their details, for example if a member of the public puts their details into an unsecure website there is a great risk of a criminal obtaining this information. Crime prevention has been massively improved with the introduction of tracking devices, CCTV (Close Circuit Television), face recognition software and hacking which can, when used correctly, be used to trace the location or activity of a criminal. Personally, CCTV has never effected or helped me, but I have known people who have had their vehicle or important items stolen from vehicles; CCTV helped them to identify the theft and in one case retrieve the stolen item.[1] This is a table showing the amount of people per year that have fallen a victim to some form of cybercrime.[2] Victims per year 556 million ...

The base of these terms and meaning made me think about different fields of science and how they terms have shaped the field. Tenner illustrates a history of these principles thru Mary Shelley the writer of Frankenstein because she pointed out “dilemmas of all science-based technology.”(Tenner 15) Shelley wrote about technology that was not developed at the time, but science and technology were a new combination for the time.

A deontologist is one who believes the rightness of an action derives not from the consequences, but from its nature. Cloning is not an action that follows the flow of naturally reproducing or how God intended us to procreate. In addition, Animal welfare becomes a big issue. The pain and suffering for example the elephant and mammoth research happening now they may have to go through can make people question the experiment all...

... Mitochondrial DNA Analysis Brandon Sanders UMUC BIOL 320 6380 Forensic Biology New Methods and Applications in Mitochondrial DNA Analysis Mitochondria are structures within cells that function as energy mediators. Each cell contains hundreds to thousands of mitochondria. We know from this class that DNA is bundled in chromosomes inside the nucleus, but mitochondria also include a very small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA. The use of mitochondrial DNA (mtDNA) sequence analysis to identify biological evidence has been well documented. More than 50 laboratories worldwide are now applying mtDNA analysis in forensic casework; e.g., to help identify human remains or to help discover the source of a shed hair. In addition, the number of mtDNA sequences added to population databases has grown rapidly. Estimates find that there are greater than 5000 sequences which have been generated in forensic laboratories, and that an equal number will be generated in the next year or two. As a result, more is known about the genetics of mtDNA, as well as the power of the system as a forensic marker. Therefore, the analysis of mtDNA is in a strong position as we approach the next millennium. Using Mitochondrial DNA as a means for human identification has quite a few features. The mitochondrial...

...What is the definition of a true hero to you? Each hero has a different meaning and role to play in order to accomplish a task. A hero doesn’t have to a be a buff person like many people think today. Famous or not, big or small, anybody in this world can be a hero. They just have to sacrifice themselves for what is right and say what they know is righteous. In the epic The Odyssey, I consider Odysseus a hero. An example of a situation Oddyseus was an actual hero was when he helped his men escape the Cyclops. According to The Odyssey, Oddyseus “tied then silently together, twinning cords of willow from the ogre’s bed; then slung a man under each middle one.” Oddyseus tied each of his men together under a sheep and tried his best to make sure...

...Wrongful conviction, often referred to as miscarriages of justice, can be defined as those who have been arrested on criminal charges, who have either pleaded guilty to the charges or have been found guilty, and, notwithstanding, their guilty plea or verdict, are actually innocent (Huff & Killias, 2010).While it may say like these situations are very rare, in fact there are many cases where innocent people are incarcerated, or even executed, because of errors in the criminal justice system. For example, as Dr. Michael Naughton, founder of the Innocence Project, which a non-profit advocacy group that works to free the wrongly convicted, said, “People think that miscarriages of justice are rare and exceptional . . . But every single day, people...
