There are several enzymes that 'unzip' DNA. These enzymes are collectively known as DNA helicases. DNA helicases are helix-destabilizing enzymes that bind to DNA at the origin of replication and break hydrogen bonds, thereby separating the two strands. This allows RNA polymerase to begin transcription (copying) of the DNA sequence.

What happens when a molecule of DNA unzips?

DNA splits, and mRNA and tRNA are there to create new strands for the new replicated DNA strand. This is what happens prior to mitosis in cell division.

How is a DNA molecule unzipped?

The original strand of DNA is unzipped by an enzyme that breaks the  hydrogen bonds between the bases. This process continues until the  entire strand of DNA has been unzipp

What happens after DNA is unzipped?

This method is called " Semi-conservative " which replicates the DNA so it begins with unzipping, unwinding the DNA by breaking down the hydrogen bonds between the nitrogenou

What enzyme unzips DNA and RNA?

The enzyme used to unzip human DNA (and RNA) is called helicase. There are a few types of helicase such as DNA helicase, RNA helicase, etc. Each type has its own specific role
