Answer 2

Answer:

The chemical name of guanine is $2$-amino-$6$-oxypurine.

Explanation:

Guanine is one of the four nitrogen bases in the nucleic acids, DNA and RNA. It belongs to a purine group while rest of the options are pyrimidines. Purines have two ringed structure composed of carbon and nitrogen atoms, and the pyrimidine group has single ringed structure. The preferred IUPAC name of guanine is $2$-amino-$1$,$9$-dihydro-$6$H-purin-$6$-one, and other names are 2-amino-6-hydroxypurine, 2-aminohypoxanthine. Guanine along with adenine, cytosine, thymine are the bases in DNA and with uracil instead of thymine forms RNA bases.
