The process of replication. The pairing of bases allows the cells to replicate, or make copies of DNA. Each base always bonds with only one other base. Pairs of bases are complementary to each other, and both sides of a DNA molecule are complementary.

∙ 12y agoMe personally? No. But the procedure you are speaking of is known as cloning. Though it is mostly illegal here in the US, many other countries have experiemented with it. Many can hardly be called successful due to medical problems with the test subjects. Long term affects have yet to be identified as it's not a widely accepted area of study, and it's creation is only 2 decades old.
The UN under it's conventions has banned any (whole) Human Cloning or otherwise creating a whole new human without the natural biological procress.
There are certain types of creatures that can make literal copies of themselves, making exact copies of their own DNA to produce offspring. See related link.

∙ 14y agoNew DNA molecules are made by copying, using old DNA molecules as a template.
Our understanding of this process also goes back to Watson and Crick's observation that only certain base pairings can exist in DNA. Each DNA strand contains the information necessary to reconstruct the other, or complementary, strand.
When a cell needs to copy a DNA molecule, it "unzips" part of the double helix, breaking the rungs of the ladder in half so that the molecule separates down the middle. New nucleotides, floating free in the cell, can then hook up with complementary nucleotides along each strand. Gradually the unzipping proceeds, and the new strands continue to grow until one DNA molecule becomes two identical DNA molecules.
A cell copies all of its DNA in this fashion each time it divides. In the cells of complex organisms such as humans, this process takes an average of 8 hours. In other words, each human cell can read and reproduce the entire genome sequence in one working day.
Scientists use a similar method to make copies of DNA in the laboratory. They put a piece of DNA in a test tube along with a bunch of free nucleotides, short DNA sequences called primers, and some enzymes that help the process along. Given the right conditions of chemistry and temperature, up to a billion DNA molecules, all identical to the original template molecule, may be produced in a matter of hours.

∙ 13y agoDNA carries the genetic information of a cell and consists of thousands of genes. Each gene serves as a recipe on how to build a protein molecule. Proteins perform important tasks for the cell functions or serve as building blocks. The flow of information from the genes determines the protein composition and thereby the functions of the cell.
The DNA is situated in the nucleus, organized into chromosomes. Every cell must contain the genetic information and the DNA is therefore duplicated before a cell divides (replication). When proteins are needed, the corresponding genes are transcribed into RNA (transcription). The RNA is first processed so that non-coding parts are removed (processing) and is then transported out of the nucleus (transport). Outside the nucleus, the proteins are built based upon the code in the RNA (translation).

DNA replicates using the process called semiconservative replication. An original DNA molecule is complementary to the replicated molecule, which means that they are identical copies of each other.
The enzymes responsible for DNA replication create copies of existing DNA which become then part of the new cell created after mitosis.
The cell would not be a cell it would be dead. It also would not be able to replicate again because it has no instructions to do so.
The deoxyribon nucleic acid lines up in perfect formation and the spindle fibers come and rip apart the DNA now there are to complete copies of DNA
i dont know if this is the answer your looking for but the new copy is called RNA its DNA minus the deoxy part

DNA replication.
A virus injects its DNA into the host cell making it produce multiple copies of that DNA and multiple copies of the protein capsule of that virus. After a while, the host cell becomes full of many copies of that virus, then the host cell explodes releasing all the new viruses. If the host cell is a bacterium and the the virus is a bacterophage, this phenomenon is done in two ways either by the lytic cycle in which virus DNA survives and the bacterial cell is destroyed,or the lysogenic cycle in which virus DNA is incorporated in the host cell DNA.
The enzymes responsible for DNA replication create copies of existing DNA which become then part of the new cell created after mitosis.
It is important for a cell to have two copies of DNA before it enters the division phase of mitosis because each new cell will require a copy of the DNA. The copies are shared between the divided cells.
A cell does not make "extra copies" of DNA. Through a persons life, DNA can only be copied so many times. The only time DNA does "copy itself" would be if a new cell is needed. For example, your skin cells die all the time and are shedded off from your skins surface. Your skin then is going to get to the point where more cells are going to be made. The DNA replicating process is what starts the process of cell mitosis (making more cells). All the DNA in your body is used, so a cell does not make extra copies of DNA. If the DNA gets destroyed, that cell dies and is replaced by another.
Assuming that no errors occurred during DNA replication, both copies of the new DNA molecules should be identical.
The cell would not be a cell it would be dead. It also would not be able to replicate again because it has no instructions to do so.
DNA is made of 2 strands so when it replicates the strands separate and 2 new strands complete the old strands. leaving 4 strands making 2 sets of DNA, both sets of DNA consist of one old strand and one new strand.- Sierra A. Buchanan
Found in RNA, google it.
DNA replication occurs because there need to be two identical copies of DNA before the nucleus of the cell divides, so that each new nucleus has a complete and identical copy of DNA.
