Question

Two nucleotides in a strand are linked through H-bond form a dinucleotide.

• A. True
• B. False

Answer 1

The correct option is B False

• The two strands of the double helix DNA have base pairing between complementary purines and pyrimidines. Adenine pairs with Thymine or vice versa by two hydrogen bonds and Guanine pairs with Cytosine or vice versa by three hydrogen bonds.
• The two nucleotides on the same strand are linked through phosphodiester bond between 5' phosphate group of one mononucleotide and 3' OH group of other mononucleotide, to form a dinucleotide.

Hence, the statement given in the question is incorrect.

So, the correct answer is 'False'.
