For the answer to the question above asking w<span>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</span>ucleic acids<span>, which include </span>DNA<span> (deoxyribonucleic</span>acid<span>) and RNA (ribonucleic </span>acid<span>), 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 </span>DNA<span>. </span>
Doing so is an example of using biology to improve human health.
