Question

6 which kind of bond holds the two strands of dna together? a covalent bonds b ionic bonds c hydrogen bonds d peptide bonds

Explanation:

In DNA, the two strands are held together by hydrogen bonds between complementary base pairs (adenine - thymine and guanine - cytosine). Covalent bonds are within a strand (e.g., between sugar and phosphate), ionic bonds are not the main bond for holding DNA strands, and peptide bonds are in proteins. So the correct option is the one with Hydrogen bonds.

Answer:

C. Hydrogen bonds
