Question

How are the monomers in nucleic acids joined?

A. peptide bonds between carbohydrates
B. peptide bonds between amino acids
C. phosphodiester bonds between amino acids
D. peptide bonds between nucleotides
E. phosphodiester bonds between nucleotides

Answer 1

E. phosphodiester bonds between nucleotides. The monomers in nucleic acids are joined by phosphodiester bonds between nucleotides.

Step-by-step explanation:

Nucleic acids are long, linear chains of nucleotides. The monomers in nucleic acids are joined by phosphodiester bonds between nucleotides. These bonds are formed by dehydration synthesis reactions, where a hydroxyl group is removed from the 3' carbon of one nucleotide and a hydrogen atom is removed from the hydroxyl group attached to the 5' carbon of another nucleotide. The result is a bond between the phosphate group of one nucleotide and the sugar of another, forming a phosphodiester bond.
