Question

during replication, the strands of a double - stranded dna molecule separate from each other when bonds are broken between their 5 - carbon sugars. amino acids. nitrogenous bases. phosphate groups.

Explanation:

In DNA replication, hydrogen - bonds between complementary nitrogenous bases (A - T, C - G) break to separate the two strands of the double - stranded DNA molecule. 5 - carbon sugars, amino acids, and phosphate groups are not the components whose bonds break for strand separation during DNA replication.

Answer:

C. nitrogenous bases
