The division of DNA is called replication.
The two strands of DNA are separated with the help of an enzyme, helicase. Each strand of DNA then "grows" a new strand along its length. The new strands are formed from free (uncombined) nucleotides. These nucleotides obey the rules of base pairing, so where the old strand has an A (adenine), the nucleotide that moves into position opposite it in the new strand has a T (thymine). Likewise C (cytosine) pairs with G (guanine).
Each old strand is described as acting as a template for the formation of the new one.
The nucleotides of the new strands are "stitched together" by enzymes called DNA polymerases.
DNA replication is called semi-conservative, because each resulting molecule of DNA has one old strand and one new one.
For more information, for example on the roles of the different DNA polymerases, and on such niceties as lagging strands and Okazaki fragments, use the links below.
What else can I help you with?
When a cell divide DNA condenses into a rod-like what?
you never did
Why does DNA make copies?
as cell divides the DNA also hav to divide to b transfferd in to newly formed cell so for that DNA divides
How do he mitochondria divide?
They have thier own DNA and ribosomes.So they replicate themselves
Does the DNA must occur before a cell can divide?
Before a cell can separate, it has to unravel its chromosomes and clone all its DNA
Is DNA condensed in S phase?
DNA is duplicated in the S phase because in the G1 phase the cell is growing and not yet ready to divide, then DNA copies as the first step for when it is getting ready to divide. In the G2 phase the cell continues to get ready to divide once the DNA is copied.
How could you determine what percentage of a strawberry's mass is DNA?
To determine the percentage of a strawberry's mass that is DNA, you would need to extract the DNA from the strawberry, quantify the amount of DNA extracted, and then divide it by the total mass of the strawberry. This calculation will give you the percentage of the strawberry's mass that is composed of DNA.
During DNA replication does the DNA molecule divide into two strands?
yes one being a strand of DNA and the other being mRNA
When cells divide what portion must be divided exactly?
The DNA.

DNA replication occurs?
The Replication of DNA does occur before the cell can divide.

How often is DNA?
DNA is copied every time a cell divides. Different types of cells divide at different rates.

Cells must copy their DNA before they do what?
Cells must copy their DNA before they undergo cell division. This ensures that each daughter cell receives a complete set of genetic information.
How often is DNA copyed?
DNA is copied every time a cell divides. Different types of cells divide at different rates.
