Deoxyribonucleic Acid (DNA) and Ribonucleic Acid are the two main nucleic acids. In all living species, DNA, the genetic material is present and can be found in cells of microorganisms (ex. Bacteria) and animals, while RNA is involved in protein synthesis. Let us have a review of the basic structure of DNA and RNA by choosing the right answers to complete the table below.

Theoretically, if the following nucleotides were to pair during RNA synthesis, how many hydrogen bonds are likely to result? a. 1 Hydrogen bond b. 2 Hydrogen bonds c. 3 Hydrogen bonds d. 0 Hydrogen bonds
DNA and RNA are chemically very similar but are distinguished, in large part, by the presence of a 2’-OH group in RNA and a 2’-H group in DNA. Why do you suppose that both DNA and RNA have 3’-OH groups and we do not typically find nucleic acids within cells that have 3’-H groups?
In what naturally occurring nucleic acids would you expectto find A-form helices, B-form helices, Z-form helices, nucleosomes,and circular DNA
Draw the DNA and RNA models in Figure 1 in the space provided. Use the legend below to represent the colored plastic chips with letters. Use lines to connect the letter representations of the plastic chips according to how they are attached to each other in Figure 1. These lines represent thechemical bonds between the different nucleic acid subunits. In the case of hydrogen bonds, specify the number of bonds such that one horizontal line corresponds to one hydrogen bond. Label the 5’ and 3’ ends of your polynucleotide strands.

Sketch a pyrimidine nucleotide subunit that would be found only in RNA. Circle and label the three components that make up this type of nucleotide. Explain what changes in the functional groups of this subunit would have to occur for it to be found in a DNA molecule.
Why do think nucleotides are also sometimes referred to as “bases” or “nucleotide bases”? What is the difference between a nucleotide and a nucleoside? Explain by giving an example, using structures. What kind of bond links a base to some sugar? Is the sugar an alpha or beta anomer? In what position(s) of the sugar does this occur? In what position(s) of the base does this occur? Instead of the term “Formation of a nucleoside”, what could the name of the reaction be? What functional group is being formed? Define the primary structure of DNA/RNA. Compare and contrast to the primary structure of proteins.
The base sequence of which type of RNA is responsiblefor determining the order of amino acids in a protein?
A nucleoside consists of an organic base, bound to ribose or deoxyribose. Draw the structure for deoxyguanosine, formed from guanine and deoxyribose.
Consider the following in light of the concept of levels of structure (primary, secondary, tertiary, quaternary)as defined for proteins.(a) What level is shown by double-stranded DNA?(b) What level is shown by tRNA?(c) What level is shown by mRNA?
Chemical analysis shows that a nucleic acid sample contains A, U, C, and G. Is this DNA or RNA? Why?
A beginning genetics student is attempting to complete an assignment to draw a base pair from a DNA molecule. The drawing is incomplete, and the student does not know how to finish. He asks for your advice. The assignment sheet shows that the drawing is to contain three hydrogen bonds, a purine, and a pyrimidine. From your knowledge of the pairing rules and the number of hydrogen bonds in A/T and G/C base pairs, what base pair do you help the student draw?
