Azt and valaciclovir are antiviral nucleoside analogs that interfere with
a. cell wall synthesis
b. viral attachment
c. nucleic acid synthesis
d. cell membrane component synthesis
e. protein synthesis

C. Nucleic acid synthesis

Explanation:

AZT, azidothymidine, is an antiviral drug used to check the viral population by blocking the process of reproduction. The azidothymidin is particularly effective against human immunodeficiency virus (HIV) as this drug inhibits the activity of reverse transcriptase which is required for the formation of a DNA copy of the RNA genome of the virus.  

Similarly, Valacyclovir is an antiviral drug that inhibits viral reproduction by blocking the DNA polymerases. The Valacyclovir serves as a prodrug of acyclovir.

Answer

The location of a gene found here is at the short arm of chromosome 17 at the specific point of the short arm of 23.6 on the chromosome.

Meaning of the address 12p7.2

12- chromosome 12

p- short arm of chromosome 12

7.2- exact point of the short arm on chromosome 12. The position of the gene on the p or q arm. The position of a gene is based on a distinctive pattern of light and dark bands that appear when the chromosome is stained in a certain way.

These addresses allow scientist and doctors to have a quick and easy way to reference specific genes to where they are which gives insight into their location.
