In a DNA strand, the nucleotides are linked together by:

Options

  1. Aglycosidic bonds
  2. Bphosphodiester bonds
  3. Cpeptide bonds
  4. Dhydrogen bonds

Correct answer

B. phosphodiester bonds

Step-by-step solution

When a phosphate group is linked to OH of 5' C of a nucleoside through phosphoester linkage, a corresponding nucleotide (or deoxynucleotide depending upon the type of sugar present) is formed.
