Question

in the process of dna replication, bonds are broken between: a bases b sugars, bases c sugars d phosphates, bases

Explanation:

DNA is a double - stranded molecule. The two strands are held together by hydrogen bonds between complementary base pairs (A - T and G - C). During DNA replication, the enzyme helicase unwinds the DNA double helix by breaking these hydrogen bonds between the bases. The bonds between sugars and phosphates (phosphodiester bonds) form the backbone of the DNA strand and are not broken during replication. The bonds between sugars and bases (glycosidic bonds) are also not broken during the replication process.

Answer:

A. Bases
