Which is a method of making new copies of DNA?

Answer 1

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.
DNA replication.

Answer 2

Me 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.

Answer 3

New 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.

Answer 4

DNA 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).

Answer 5

That happens every time a cell divides.

Answer 6

DNA Replication.

...THAT IS ALL.

Answer 7

DNA replication.
