Question

During DNA replication, the strands separate by
(a) DNA polymerase
(b) topoisomerase
(c) unwindase/helicase
(d) gyrase

Answer 1

Answer:

all above these.except DNA Polymerase 1.

Answer 2

During DNA replication, the strands separate by unwindase/helicase.

Explanation:

• The process through which the DNA makes the copies of itself is called as DNA replication.
• This process occurs during the division of cell.
• The unzipping of the DNA's double helix structure is the first thing associated in the replication of DNA.
• The two single strands of DNA separates and creates a replication fork which is in Y shape.
• The enzyme called  DNA helicase helps in the melting of hydrogen bonds that holds the DNA 's double helix structure.
• This is called as Unwindase or helicase.
