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.

DNA divides through a process called replication, where the double-stranded DNA molecule is unwound and each strand serves as a template to synthesize a new complementary strand. This results in two identical copies of the DNA molecule that can then be distributed into two daughter cells during cell division.

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
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 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
What happens to DNA and chromosomes when cells in most parts of the body divide?
During cell division, DNA replicates to form two identical copies that are then separated into two new cells. Chromosomes condense, align at the center of the cell, and are pulled to opposite ends during cell division. This ensures that each new cell receives a complete set of chromosomes with the same genetic information.
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.
Why is an replication of DNA essential in al cells?
DNA replication is essential in all cells to ensure accurate transmission of genetic information from one generation to the next. Replication allows for the faithful duplication of the genetic material to be passed on during cell division. It also enables genetic diversity through mutation, providing the basis for evolution and adaptation.
When does DNA replacation occur?
DNA replication occurs during the S phase of the cell cycle, which is the phase where DNA is synthesized and duplicated in preparation for cell division. This process ensures that each daughter cell receives an exact copy of the genetic material.
What is the role of centrioles?
Centrioles are involved in organizing the microtubules during cell division. They help in the formation of the spindle apparatus, which is essential for separating chromosomes during mitosis. Additionally, centrioles are important for the formation of cilia and flagella in some cells.
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.
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
DNA replication occurs?
The Replication of DNA does occur before the cell can divide.
How cells divide and reproduce?
Cells divide through a process called mitosis, where a cell duplicates its DNA and separates into two identical daughter cells. This allows cells to reproduce and grow, maintaining tissue and organ function in the body. Errors in cell division can lead to mutations and diseases such as cancer.
