The area of the picture highlighted by the green square is a monomer of nucleic acids(DNA/RNA). Which of the following is the name for that monomer? A. phosphate backbone
B. thymine
C. nucleotide

C. Nucleotide

Explanation:

There are four types of biological molecules existing in nature. These are: carbohydrates, proteins, lipids, and nucleic acids. Nucleic acids are biological polymers made up of monomeric units called NUCLEOTIDES.

A nucleotide as depicted in the attached image is a molecule made up of three components namely; Penrose sugar, phosphate group, and nitrogenous base (adenine, guanine, cytosine and thymine). Based on the image in this question;

A represents ADENINE

S represents SUGAR

P represents PHOSPHATE GROUP

Hence, the monomer is a NUCLEOTIDE.
