The bond which connects a nitrogenous base with deoxyribose sugar in a nucleotide of DNA molecule is

NUCLEIC ACIDS
NEET
1

Hydrogen bond

2

Glycosidic bond

3

Ester bond

4

Phosphodiester bond

Solution:

A nucleotide is composed of a nitrogenous base, a pentose sugar (deoxyribose in DNA), and a phosphate group. The nitrogenous base is linked to the 1' carbon of the pentose sugar by an N-glycosidic bond. The phosphate group is attached to the 5' carbon of the sugar by a phosphoester bond. Phosphodiester bonds link adjacent nucleotides in a polynucleotide chain. Hydrogen bonds are involved in pairing between complementary bases in the DNA double helix.
