In prokaroytes, it is the RNA polymerase (holoenzyme). Different proteins make up the holoenzyme and one of them is known has beta'. It is in charge of binding DNA and unwinding it.

Since DNA consists of two mirror images, it has copied itself by unwinding.

Which job must enzymes do before replication can begin?
They must unwind part of the original DNA molecule.
What must happen to the DNA before transcription can take place?
It must unwind and separate for transcription to occur
What is the difference between helicase and topoisomerase?
Helicase unwind the two DNA strands while topoisomerase unwind and also rejoin the the two strands of DNA.
What happens first at each origin replication?
Enzymes unwind DNA!
A zebra cell is just about to replicate its DNA What happens first?
Enzymes unwind the DNA molecule into two strands.
Which job must enzymes do before replication can begin?

It must unwind and separate for transcription to occur
What is the difference between helicase and topoisomerase?
Helicase unwind the two DNA strands while topoisomerase unwind and also rejoin the the two strands of DNA.
Which structure forms as DNA unwind?
A replication bubble.
Why important of helicase?
To unwind the DNA double helix
What do heliocases do?
separate strands of nucleic acids (unwind DNA)
What happenes first at each origin of replication?
Enzymes unwind DNA!
What happens first at each origin replication?
Enzymes unwind DNA!
A zebra cell is just about to replicate its DNA What happens first?
Enzymes unwind the DNA molecule into two strands.
Can DNA polymerase unwind DNA?
Short Answer: There are almost a dozen different types of DNA polymerase: some may have a subunit that performs the unwinding functions.
What is the helicase enzyme?
Unwinds the DNA during DNA replication and Trancription
Why must the DNA In a cell replication before the cell divides?
DNA replication begins when the two sides of the DNA molecule unwind and seperate, like a zipper unzipping.
