Question

What is the point at which dna strand is unzipped so that it can form new complimentary strands?

Answer 1

That is the first point of DNA replication where the DNA is treated with DNA helicase which breaks the hydrogen bonds between the DNA strands causing them to unzip to form 2 new template strands

hope that helps

Answer 2

Answer:origin point.

Step-by-step explanation:

Before deoxyribonucleic acid (DNA) replication starts, two DNA strands separate from each other. This is effected by the action of an enzyme known as helicase which breaks the hydrogen bonds between the two strands allowing them to separate. The point at which this separation begins is known as the origin point.
