B. Below is the structure of the nucleoside analog azidothymidine (AZT). AZT was used as an early HIVIAIDS therapy that inhibited replication by the human immunodeficiency virus (HIV) by blocking synthesis of viral DNA. NH HO i) (2 points) Before its incorporation into viral DNA, AZT is converted in the cell to the nucleoside triphosphate. Draw the structure of azidothymidine triphosphate with all ionizable groups in the ionization states expected at pH 7. (Note: the azido group will appear at...

1. Very simple toy model for base-pairing of double stranded DNA. (This problem is originally due to Kittel.) DNA is an important biological heteropolymer. A single DNA molecule base-pairs with a complementary DNA molecule to form a duplex double stranded structure. Consider two strands of complementary DNA. Each strand has N monomers. Each monomer is cross- linked by base-pairing to the corresponding monomer on the complementary DNA molecule. Suppose that the energy for breaking a cross link is є and...

Question 8 1 pts Base pairing is an essential property of a DNA helix. Its presence or absence is very important for all of the following EXCEPT: Establishing the 5' to 3' polarity of a piece of DNA Providing a primer for DNA polymerase. Identifying an origin of replication. Identification of a damaged nucleotide that needs to be repaired. The use of a template to make a new daughter strand Question 9 Primase is an essential component of the replication...
