What is the area of biology that studies the nucleic acid makeup of an organism?

For the answer to the question above asking w hat is the area of biology that studies the nucleic acid makeup of an organism?

I think the answer is Microbiology because of the nucleic acid thing. Since n ucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides. Each nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base. If the sugar is deoxyribose, the polymer is DNA.
