...Importance of DNA - A T2 Assessment Understanding what DNA is, is very important. DNA is the material that carries all the information about how a human will look (facial features, etc,.) and also how they will process daily. For example, DNA in humans determines things such as what color the eyes are, what color the hair is, and also what gender you are when a baby. DNA is found in the nucleus of almost all cells. DNA also does something called replicating nucleotides. If DNA never replicated, cell life would be impossible. If this really were to happen, the cells would then die. DNA replicates itself in order to create more DNA strands for cells. It happens along the entire DNA molecule. It continues this until the entire strand/ladder...

...DNA DNA or Deoxyribonucleic acid is the very building block needed in the creation of life. It is composed of genetic instruction to map out the creation of an entire organism. DNA is well suited in the storage of biological information. Yet with all of this complex information there are certain chemicals or forms of energy that can damage or alter this special coding. In process of damaging or altering the coding of DNA the most dreaded situation of a cancerous cell can be formed. To start let’s look at the different kinds of radiation that may or may not effect DNA. Alpha, Beta, and Gamma Radiation Ionizing Radiation can change the way our body’s work and develop. Direct includes covalent linkage between nitrogenous bases, and creating structure like thymine dimmers. Indirect is when it interacts with water to create free radicals which can interact with a person’s DNA. It can cause single or double stranded breaks in the sugar- phosphate backbone. (Buttons, n.d.) Alpha Radiation is a process that needs to be swallowed, inhaled, and or absorbed into the blood stream. This can increase the risk of cancer also known as lung cancer. Radon is a silent but deadly killer. To determine if one has been affected by alpha particles testing would be completed with special equipment and gear to prevent those from any exposure. Beta Particles can be a helpful process of treatment to many, such as treating thyroid disorders, cancer, and Graves’ disease (hyperthyroidism). It also...

...head: SIGNIFICANCE OF DNA Significance of DNA Significance of DNA Deoxyribonucleic acid (DNA) was first discovered in 1869 by Johann Friedrich Miescher, but it was not until the 1950s while studying viral replication did Alfred Hershey and Martha Chase determine DNA was Genetic material. In 1953 James Watson and Francis Crick discovered DNA was a double helix (a double helix looks like a twisted ladder). The discovery of Watson and Crick opened the door helping describe the significance and importance of DNA as the molecule of inheritance while addressing the structure of the DNA molecule, and why is a molecule of DNA so perfect for the job it performs. I will look at what exactly does DNA code for, how is that translated into actual traits, what are mitosis and meiosis, what are the similarities and differences, and what do mitosis and meiosis allow for. I will show how traits are passed from parents to offspring and lastly describe how knowledge of DNA and genetics can help in my life. The Significance and Importance of deoxyribonucleic Acid (DNA) as the Molecule of Inheritance The significance and importance of DNA “is the body’s instruction manual for making you who you are. It is present in any living being. It carries all the instructions and materials the body needs to function”(Leving, 2008). The DNA in cells is all the same for individuals, which create a specific identity for each individual. Discuss Briefly the structure of the DNA Molecule and Why is...

...In 1962 James Watson along with Francis Crick and Maurice Wilkins were awarded a Noble Prize for the paper that they published about the discovery of the double-helix model of deoxyribonucleic acid or DNA. The discovery of the helical structure of DNA is considered as one of the most important achievements in the field of the science history. However, James Watson does not deserve the recognition of discovering the helical model of DNA. Watson should lose his nobel prize, not only did he not give any credit to the person who was really the one responsible in discovering the helical shape of DNA he is also making rude and prejudiced opinions. Few people know Rosalind Franklin, a scientist who devoted herself in the scientific study of the structure...

...Genetic disorders are inherited from an individual’s parents through the gamete cells that ultimately develop into the offspring. There are three major inheritance patterns that were highlighted: single gene, chromosomal, and multifactorial disorders. It is important for pediatricians to understand both the disorders and the diagnostic tools used due to disorders beginning at conception. Due to the multitude of ways that genetic disorder can arise, there are different diagnostic tools that can be used to determine a disorder. This review article used an exploratory study that used previous papers to highlight, identify, and merge diagnostic techniques into a single paper. The major data and results from this paper focused on what the diagnostic...

...genetic material for desirable traits n production, drought resistant and pest resistant. From traditional practices, selective breeding practices have continuously improved the agricultural sector (Liang, & Skinner, 2004). Selective breeding is the control of breeding in plants and animals by taking the desired and high producing plants for the hybrid to have the best produce overtime. Researchers took selective breeding in the 20th century to understand the main components that caused changes difference in plants and animals. In 1859 Charles Darwin brought up the theory of origin grouping different organisms to species that made great steps to understanding breeding of species. This knowledge led to discoveries of genetics and genes that make up the different species by Gregor Mendes in 1865. The discovery of the nucleus and DNA sequence by...

...Escherichia coli With pGalTM OBJECTIVE: To develop an understanding of bacterial transformation by plasmid DNA, and determine the transformation efficiency of a bacterial sample. INTRODUCTION: Transformation is an important biological mechanism for generating genetic diversity in the natural world. It is also one of the most used tools used in modern biotechnology. It has allowed for a lot of genetic engineering advances. Scientists can design and build DNA containing genes they want and then transfer these genes into bacterial cells that they can get to express those genes. This is a very basic technique that is used on a daily basis in a molecular biological laboratory. This is based on the natural function of a plasmid: to transfer genetic information vital to the survival of the bacteria. Transformation is an example of horizontal gene transfer. There are three mechanisms for horizontal gene transfer in bacteria. Conjugation is the transfer of DNA from one cell to another through conjugation pili. Transduction is the transfer of genes between bacterial cells using a bacteriophage (a type of virus). Transformation is the ability of cells to take up freely floating DNA found in the environment. Bacterial cells that are able to take up free-floating DNA from the environment are called competent cells. Bacteria are not always competent. When growth conditions are optimal, most bacteria cannot uptake DNA. In most cases, in response to some stimuli (such as stressor...

...An important factor in the structure of DNA is the amino acids. Amino acids are the building blocks of proteins. In the process of allowing for the function to occur, it must go through several different steps. The structure of DNA leads to the structure of proteins because structure matches function (ISN pg. 110). When DNA is translated an error can occur, and these errors are called mutations. Mutations are a random change in an organism's DNA. Some mutations can be positive and provide survival advantages. Mutations can also be neutral and not hurt or help. Mutations can be negative and act as a disadvantage. Consequently, whether a mutation is positive, negative, or negative depends on the environment in which the organism is living. For example, a mutation could provide camouflage in an environment, or it could draw attention to the...

...3/27/12 English 90 The hunger games In the book by Suzanne Collins “The Hunger Games”, Katniss goes on to achieve atonement because she was “at-one” with her new self and life. In her journey Rue, one of the tributes that became Katniss’ ally, was killed. Katniss had to absorb the changes caused by the journey and she was fully reborn, after Rue’s death. This made Katniss balance herself by understanding, accepting, and realizing what she had to do. I believe this made katniss a hero because of the atonement. First of all, Katniss starts to understand what Haymitch wanted all along. In this quote, “one kiss equals one pot of broth.”(p.261) Katniss realizes that Haymitch wanted her to give the audience more. She had to show romance between herself and Peeta. This made her more powerful in a way because she just had to kiss Peeta and show romance. Then she would receive a gift. Katniss understood what Haymitch wanted her to do. Second of all, Katniss starts to trust and she starts to accept Peeta. In this quote “This is the first kiss where I actually feel stirring inside my chest” (p.298) and she realizes that she wants another kiss. This means that she is starting to accept Peeta in a romantic way. In this other quote, “No one has held me like this in such a long time.” (p.299) she feels like she is beginning to trust him because no one had ever held her like that in a...

...As a nurse one runs into some very saddening/ maddening situations, some that cause not only the individual nurse, but the entire nursing staff to be thrown into conflict with their beliefs of non-maleficense and a patient’s right to autonomy. I always strive to never cause any harm to a patient and treat them kindly despite behaviors that could lead one to not want to act or treat someone is such a manner. Additionally I believe an individual should also have the right and be supported in making decisions about their healthcare, but when the decision is in effect, taken away from them, who has that right? When the nurse and stand staff struggle with the decision that is being made, it complicates the picture, leads to a lot of frustration and nurses feel helpless Several years ago there was an incident of a pt that received a kidney transplant, but during the immediate post operative course the patient, suffered a respiratory arrest, was anoxic for a period of time leaving the pt with anoxic brain damage. This was an individual who, prior to surgery, was a fully functional person. After time in the ICU the patient was able to be on the nursing floor; trached, unable to swallow, g-tube, very limited ability to walk, or transfer to a chair w maximal assistance of typically 2 staff members. The individual also tended, what seemed to be intentional, to try and injure nursing staff, by pinching, kicking and biting.. I was often assigned to this pt, and on several occasions...
