The following diagram represents a nucleotide that serves as a monomer for ribonucleic acid (RNA). Classify this nucleotide as purine or pyrimidine base. Label the group or atom that you would remove, so that the nucleotide drawn above can serve as a monomer for DNA. What type of bonds would hold two such adjacent nucleotides together in a growing nucleic acid chain? Circle the group(s) that would participate in the formation of this bond if the nucleotide shown above, was added to the growing nucleic acid chain. Name the type of bonds that the above nucleotide will form with its complementary nucleotide. How many of these bonds would you expect between this nucleotide pair? The nucleotide (N) shown above is a part of the following nucleic acid sequence. 5\'GGCCAAACCA3\' For the nucleic acid sequence that is given above, Which nucleotide base (A/T/G/C/U) has a free phosphate group? Which nucleotide base (A/T/G/C/U) has a free hydroxyl group? If adenosine (A) is added to the above nucleic acid sequence in a cell, would it be added to the 5\' end or the 3\' end? The nucleic acid sequence shown above interacts with a specific protein. Of the following amino acids that are a part of this protein, circle those whose side-chains are most likely to interact with the phosphates of the sugar-phosphate backbone of nucleic acids. Explain why you selected these amino acids. Methionine, Lysine, Alanine, Leucine, Arginine

Solution

Ans.)

a) It is clear from the given structure i.e. pyrimidine ring fused to an imidazole ring that it is a purine base.

b.) If the hydrogen atom from C2 is removed then the given nucleotide become monomer of DNA.

c.) Hydrogen bond is found the nucleotides in DNA.

d.) Phosphodiester bonds is found in complimentary nucleotide.
