Question

______ carbon atoms of successive nucleotides of nucleic acid are linked by Phospho-diester bond.

विकल्प

• C₅ - C₄

• C₅ - C₃

• C₅ - C₁

• C₅ - C₂

Answer 1

C₅ - C₃ carbon atoms of successive nucleotides of nucleic acid are linked by Phospho-diester bond.

Explanation:

Phosphodiester bond in nucleotides occurs mainly between CS and C3 positions. So the direction of synthesis is always 5' to 3 '.
