Question

The bond present between two nucleotides is known as (A) Phosphoester linkage (B) Phosphodiester linkage (C) Glycosidic linkage (D) Peptide linkage

Tardigrade Admin · Accepted Answer

In a polynucleotide, two nucleotides are joined by phosphodiester bond which is formed between 3' OH of first nucleotide and 5' PO4-3 of second nucleotide. Thus a polynucleotide chain consist of two free ends, 5' PO4-3 and 3' OH.

Q. The bond present between two nucleotides is known as

Phosphoester linkage

Phosphodiester linkage

Glycosidic linkage

Peptide linkage

In a polynucleotide, two nucleotides are joined by phosphodiester bond which is formed between 3' OH of first nucleotide and 5' PO_4^-3 of second nucleotide. Thus a polynucleotide chain consist of two free ends, 5' PO_4^-3 and 3' OH.
