Answer:
C. an amino acid
Explanation:
Nucleic acids are one of the four biological molecules found in living systems, which function in the storage and transmission of genetic information. Nucleic acids are polymers and like every other polymers, they are made up of monomeric units called NUCLEOTIDES joined together by covalent bonds called phosphodiester bonds.
NUCLEOTIDE is structurally composed of three major components viz:
- A five-carbon sugar: This can either be ribose or deoxyribose depending on whether the nucleic acid is a RNA or DNA respectively.
- Nitrogenous base: The four nitrogen-containing bases found in nucleic acids are Adenine, Guanine, Cytosine, Thymine (DNA) or Uracil (RNA).
- Phosphate group
