Which enzyme unwinds the DNA helix ?

Choose the correct answer from the choices given under each bit. During replication of DNA, which of the following enzymes unwinds the double helix?

Observe the given figure. Which enzyme might be responsible here for releasing the tension in the DNA helix?

The enzyme that unwinds DNA molecule is ligase(true/false)

..................... are enzymes that unwind DNA helices while .................. break and reseal the strands.

The enzyme that reduces the tension during the unwinding of DNA helix in front of the replication fork is :

Answer the following in one word only. The enzyme that unwinds DNA is

Arrange the following steps in correct order: (DNA replication): (I) Topoisomerase stabilises the helix in phases. (II) Okazaki fragments are formed during DNA replication. (III) Helicase unwinds the helix in phases. (IV) Ligase joins the Okazaki segments
