DNA Helicase Enzymes Move in What Direction Along the DNA

Question

DNA helicase enzymes move in what direction along the DNA during DNA replication?
A) 5' to 3'
B) 3' to 5'
C) They remain stationary

Accepted Answer

DNA helicase enzymes move in the 5' to 3' direction along the DNA during DNA replication. This is because the enzyme unwinds the double-stranded DNA in the 5' to 3' direction, and as it does so, it moves along the DNA strand in the same direction.
