"To unwind the duplex DNA" is the one among the following choices given in the question that shows the role of DNA helicase during DNA replication. The correct option among all the options that are given in the question is the first option. I hope that this is the answer that has actually come to your great help.

Answer:

The correct answer is to unwind the duplex DNA.

Explanation:

DNA helicase is the first essential enzymes during replication which unwinds the double stranded DNA at the origin of replication.

DNA helicase works in a manner as follows:

1. Helicase binds to the origin of replication where synthesis will start.

2. Enzyme starts unwinding the double-stranded DNA by melting the hydrogen bonds between them using energy in the form of ATP.

3. Enzyme continues the process of unwinding the DNA by forming a structure called the replication fork.

Thus, the correct answer is to unwind the duplex DNA.
