What type of bond links the 3’-carbon of one sugar of one nucleotide to the 5’-carbon of the sugar of the succeeding nucleotide in a nucleic acid?
Options
- APeptide bond
- BGlycosidic bond
- CEster bond
- DPhosphodiester bond
Correct answer
D. Phosphodiester bond
Step-by-step solution
In a nucleic acid, a phosphate moiety links the 3’-carbon of one sugar of one nucleotide to the 5’-carbon of the sugar of the succeeding nucleotide. The bond between the phosphate and hydroxyl group of sugar is an ester bond, and as there is one such ester bond on either side, it is called phosphodiester bond.
