What else can I help you with?
Which job must enzymes do before replication can begin?
They must unwind part of the original DNA molecule.
Will DNA unwind as a result of a mutation?
after mutation two kinds of effect may take place. good or bad. in case of plant good yieldin, big fruits etc.. are found but in man usually it make a bad effects. klinfilter syndrome, sikkle cell aneamea are some of such diseases.
What must happen to the DNA before transcription can take place?
Before transcription can take place, the DNA in the cell nucleus must be unwound and separated into two strands by enzymes. This process exposes the genetic information that will be transcribed into mRNA.
Which which job must enzymes do before replication can begin?
Unwind part of the original DNA molecule :)
How can DNA be denatured?
DNA can be denatured by exposing it to high temperatures or extreme pH levels, causing the double helix structure to unwind and separate into single strands.
Which job must enzymes do before replication can begin?
They must unwind part of the original DNA molecule.
Why important of helicase?
To unwind the DNA double helix
Which structure forms as DNA unwind?
A replication bubble.
Can DNA polymerase unwind DNA?
No, DNA polymerase cannot unwind DNA. DNA polymerase is responsible for synthesizing new DNA strands by adding nucleotides to a template DNA strand. The unwinding of DNA is typically performed by DNA helicase enzymes.

What happenes first at each origin of replication?
Enzymes unwind DNA!

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.
How does DNA copy it self?
When chromosomes are duplicated before mitosis or meiosis, the amount of DNA in the nucleus is doubled. The Watson and Crick model shows how this takes place. The two sides of DNA unwind and separate. Each side then becomes a pattern on which a new side forms. The new DNA has bases that are identical to those of the original DNA and are in the same order.
What happens first in DNA replication?
base pairs are broken apart
What in the cell helps DNA unwind?
