...Associate Program Material DNA Worksheet Answer the following in at least 100 words: Describe the structure of DNA. 1. A DNA molecule consist of very long chains of monomers and polymers that are known as nucleotides. The grouping of the nucleotides into the polynucleotides then forms these two chains in particular which composes of DNA strain. The nucleotide is made up of a nitrogenous base, of sugar and of a phosphate group. In the DNA case, there are four nucleotides that are found along the DNA chain, the four nucleotides ate (T) thyme, (A) adenine, (C) cytosine, and (G) guanine. These four nucleotides are joined together by their covalent bonds, or more specific, the phosphates and the sugar, which composes the sugar/phosphate, back bone of the polynucleotide. 2. How does an organism’s genotype determine its phenotype? The genotype of the organism is the genetic make up of that organism, it’s the nucleotide base in the organisms DNA. The phenotype is considered the physical traits of the organism, which comes from the actions of various proteins. Structural proteins make up the structure of an organism and the enzymes catalyze the metabolic activities. Protein is not built by a gene, but it gives the instructions to do so in the form of RNA, which programs the synthesis of the protein. 3.

...Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA nucleotide bases consist of a particular code and specific strands of this code are termed genes. A gene will code for particular proteins which will end in a specific trait. The base pairing in a DNA molecule is specific: Adenine always pairs with Thymine and Guanine always pairs with Cytosine. A gene segment from DNA will give the directions necessary to build a RNA molecule which finally can be translated into a protein. 2. How does an organism’s genotype determine its phenotype? An organism's genotype is its specific combination of alleles for a given gene and the phenotype is the physical indication of an organism's allelic combination. A trait is the acquired or inherited characteristics shown in a phenotype. * 3. Describe each stage of the flow of information starting with DNA and ending with a trait. * A sequential set of nucleotides in the DNA are transcribed into a molecule of RNA in the cell’s nucleus. Translation of the RNA into a specific amino acid sequence of a protein occurs after the RNA travels to the cytoplasm. “The molecular “chain of command” is from DNA in the nucleus to RNA to protein synthesis in the cytoplasm. The two main stages are transcription, the transfer of genetic information from DNA into an RNA molecule, and translation, the transfer of the information from RNA into a protein...

...Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. The three-dimensional structure of DNA – the double helix – arises from the chemical and structural feature of its two polynucleotide chains. Because these two chains are held together by hydrogen bonding between the bases on the different strands, all the bases are on the inside of the double helix, and the sugar-phosphate backbones are on the outside. In each case, a bulkier two ring base is paired with a single-ring base; A always pairs with T, and G with C. In this arrangement, each base pair is similar width, thus holding the sugar-phosphate backbones an equal distance apart along the DNA molecule. To maximize the efficiency of base-pair packing, the two sugar-phosphate backbones wind around each other to form a double helix, with one complete turn every ten base pairs. 2. How does an organism’s genotype determine its phenotype? An organism’s genotype, its genetic makeup, is the sequence of nucleotide bases in its DNA. The phenotype, the organism’s physical traits, arises from the actions of a wide variety of proteins. Structural proteins help make up the body of an organism, and enzymes catalyze its metabolic activities. DNA specifies the synthesis of proteins. However, a gene does not build a protein directly, but rather dispatches instructions in the form of RNA, which in turn programs protein synthesis. This molecular...

DNA Fingerprinting: An Application Although a rare occurrence, cases of babies switched at birth in a hospital have made the news in the past. Since an individual’s DNA sequence is unique, with the exception of identical twins, DNA fingerprinting is a reliable method used to determine the parents of a given baby. DNA fingerprints can be derived from restriction fragment-length polymorphism analysis or using the polymerase chain reaction with variable number tandem repeats. In this activity, you will analyze the results of a DNA fingerprint conducted on three babies and three sets of parents to determine which baby belongs to which parent.

...DNA Worksheet REVISED Part1: Basic structure of DNA The nucleotide bases of a DNA consists of specific codes and particular strands of this codes are known as the genes. The genes codes for a particular protein which eventually be a specific trait. The pairing of the base in a DNA molecule is very specific. Adenine usually pairs with Thymine while Guanine normally pairs with Cytosine. A segment of a gene from DNA usually gives the necessary directions to build a RNA molecule and eventually translated into a protein (Simon, Reece and Dickey, 2010). Reason why DNA is referred to as a protein recipe DNA is referred to as a protein recipe because its molecules are made up of amino acid proteins which are in form of a long strand. The DNA structure is composed of codons. Basically, the DNA codes for RNA codon or a transcription which is used to form proteins which is the translation of the codon. Each group of tri-codons are then read by the ribosomes where for each group of 3 such codons, there is an amino acid. These amino acids are then bound together to make a protein chain. The complexity of a protein depends on the number and type of chains (Simon, Reece and Dickey, 2010). Part 2: Differences between DNA and RNA DNA is used for long-term storage of genetic information, transmission of genetic information so as to make other cells and new organisms and to transfer the genetic code to the ribosomes from the nucleus to manufacture proteins. On the other hand, RNA is used...

...BIOL2103 Biological Sciences Laboratory Course Practical 3 Laboratory manual Isolation of nucleic acid and spectrophotometry Introduction: The ability to isolate and quantify nucleic acids accurately and rapidly is a prerequisite for many of the methods used in biochemistry and molecular biology. The concentration of DNA or RNA in a sample, and its condition, are often estimated by running the sample on an agarose gel. Such concentration estimates are semiquantitative at best and are time-consuming. For a more accurate determination of the concentration of DNA or RNA in a sample, a UV spectrophotometer is commonly used. Spectrophotometry uses the fact that there is a relationship between the absorption of ultraviolet light by DNA/RNA and its concentration in a sample. The absorption maximum of DNA/RNA is approx 260nm. The purity of a solution of DNA can be determined using a comparison of the optical density values of the solution at various wavelengths. For pure DNA, the observed A260/A280 ratio will be near 1.8. Elevated ratios usually indicate the presence of RNA. The A260/A280 ratio is used to assess RNA purity. An A260/A280 ratio of 1.8-2.1 is indicative of highly purified RNA. The 260/280 ratio below 1.8 often signal the presence of a contaminating protein or phenol. Alternatively, protein or phenol contamination is indicated by 230/260 ratios greater than 0.5. Workflow Time 2 days before the lab session During lab session 1:30 pm Task Cell...
