Question

1. the complementary strands of the dna molecule are held together by * 6 points weak bonds that unzip during replication called _______________. ionic bonds peptide bonds hydrogen bonds polar bonds

Explanation:

In DNA, the two complementary strands are held together by hydrogen bonds between the nitrogen - containing bases. These hydrogen bonds are weak and can be broken during DNA replication to unzip the strands. Ionic bonds are not involved in holding DNA strands together. Peptide bonds are found in proteins, not in DNA. Polar bonds are a general type of covalent bond and not the specific bond holding DNA strands together.

Answer:

C. hydrogen bonds
