1. Describe the three parts of a nucleotide and how they bond to form a nucleotide.
The three parts of a necleotide are a carbon sugar, a phosphate group and a nitrogenous base. The carbon sugars bond to the phosphate groups by covalent bonds while the nitrogenous base bonds with it’s compliment by hydrogen bonds.
2. Summarize the role of covalent bonds and hydrogen bonds in the structure of DNA. The role of covalent and hydrogen are as follows. hydrogen bonds, being easy to break, allow the DNA to break so that copies can be made. Whereas covalent bonds keep the sugar and phosphate together, which allows proper placement and structure.
3. Relate the role of the base pairing rules to the structure of DNA. The bases in a strand of DNA relate to the base pairing rule due to the combination of GC and AT, make equal strand, that is held together by a hydrogen base.
4. What is the primary function of DNA? What is DNA long chains of? The primary function of DNA is to code for information. DNA consists of long chains of amino acids.
5. State the names of the nitrogenous bases using purines and pyrimidines . The bases in a strand of DNA relate to the base pairing rule due to the combination of GC and AT, make equal strand, that is held together by a hydrogen base.
6. Explain Chargaff’s rule of base-pairing.
Chargaff observed that the percentage of adenine equals the percentage of thymine, and the percentage of cytosine equals that if guanine in the DNA of a variety of organisms. So being opposites, they attract. A to T and C to G.
7. Show how dehydration synthesis (condensation reaction) bonds occur at 2,3 and 5 prime carbons of sugar. Monomers join together to form polymers by removing water to form covalent bonds. It takes OH from sugar on the 5th carbon and takes H from phosphate group to...
