Question

The bonds found in a polynucleotide chain between the individual nucleotides and nitrogen bases are

• A. Peptide bond, Hydrogen bond
• B. Hydrogen bond, Peptide bond
• C. Phosphodiester bond, Hydrogen bonds
• D. Glycosidic bond, Phosphodiester bond

Hint:

Phosphodiester bonds link nucleotides; hydrogen bonds link base pairs in DNA.

Answer 1

The Correct Option is C

In DNA, nucleotides are linked by phosphodiester bonds to form the backbone of the strand, while complementary nitrogenous bases are joined via hydrogen bonds across the strands. Peptide bonds are found in proteins, not nucleic acids.
