Answer:
D. Bonds between the strands are relatively weak hydrogen bonds, whereas bonds within the strands are relatively strong covalent bonds
Explanation:
According to Watson and Crick hypothesis on the structure of the deoxyribo nucleic acid, the two double helix strands of the DNA are weakly associated with each other by hydrogen bond. Within the strands, the nucleotide bases are held together by covalent bonds.
<em>The weak hydrogen bond ensures that the two strands are easily separated by the relevant enzyme during the process of replication or transcription. The relatively stronger covalent bond ensures that the nucleotide chains are not broken during the separation of the two strands.</em>
The correct option is D.
