Question

Adjacent nucleotides in a polynucleotide chain are
joined by
(1) N-glycosidic bond
(2) Phosphodiester bond
(3) O-glycosidic bond
(4) Hydrogen bond​

Answer 1

Answer:

answer is (2) Phosphodiester bond

[Pentose sugar+Nitrogen base =nucleoside

linkage : n-glycosidic bond]

[nucleoside+phosphate =nucleotide

linkage: phoshoester bond]

[nucleotide+nucleotide=polynucleotide

linkage: phoshodiester bond]

hydrogen bonds are exist between adjacent nitrogen bases
