What does the term "unzipping" refer to in dna replication? a. polymerization b. breaking hydrogen bonds c. the movement of dna polymerase d. matching complementary nucleotides

B. breaking hydrogen bonds

Explanation:

DNA replication is an important phenomenon that must occur in every living cell that is about to undergo division. It is a process of doubling the content of the genetic material (DNA) in the cell so that each daughter cell can get a correct amount of DNA. However, prior to replication of the DNA, its long double-helical structure needs to be unzipped.

This unzipping is carried out by an enzyme called DNA HELICASE. It is the process of separating the double-strands of the DNA into two single strands that forms a Y-shaped replication fork. This unzipping is actually done by breaking the weak hydrogen bonds that holds the complementary nucleotide subunits together. Each separated single strand serves as a template for the synthesis of a new DNA strand.

answer; i believe that the correct answer is (b) melosis; plz check first.good luck
