DNA (deoxyribosenucleic acid) replicates by a process called semi-conservative replication. In semi-conservative replication, one side of the DNA structure as acts a template and guide for the other strand to copy. Floating nucleotides then match up with the corresponding base (adenine base pairs with thymine, and cytosine base pairs with guanine). This pairing system is known as complementary base pairing.
The fact that one side is copied exactly like the other, and the bases are always joined in the same sequence means the chances of a mutation is lessened, hence the two copies are exactly like the original DNA.

How do the new copies of DNA compare to the original DNA?
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.
How are the new strands and the original strands of DNA divided between the two new cells?
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
Why do new copies of DNA have to be similar to the original strand?
New copies of DNA have to be identical to the original strand so that the cells can function properly. If mistakes are made in DNA replication, it could cause a mutation to occur. In body cells, that means the possibility of tumors, including cancer. In gametes (sperm and egg cells), this could mean are very harmful genetic disorder, or it could be so bad that the organism produced by fertilization may not be able to survive.
When DNA splits a new 'what' of DNA is formed?
A new strand of DNA exactly alike to the original is created.
How does DNA semi-conservative replication help prevent mutations in DNA replication?
Semi conservative replication prevents mutations during DNA replication because it produces 2 copies that each contained 1 of the original strands and 1 entirely new strand.

How is anything genetically modified?
Scientists have the means to extract the DNA strand from a cell. Once the DNA strand is removed, it can be altered, then placed back into the cell. When the cell divides and multiplies - the new copies will retail the altered DNA rather than having the original.

A new strand of DNA exactly alike to the original is created.

Semi conservative replication prevents mutations during DNA replication because it produces 2 copies that each contained 1 of the original strands and 1 entirely new strand.
When DNA replicates the new strand is what to the original strand?
The original strands provide a template for making new strands.
What is the role of the DNA new strand?
It is a copy of the Dna original strand.
What does semiconservative replication refer to?
Semi-conservative replication refers to the normal process of the synthesis of DNA. It produces two copies of DNA, each containing one of the original strands and one entirely new strand.
What gives a cell DNA?
The enzymes responsible for DNA replication create copies of existing DNA which become then part of the new cell created after mitosis.
Why is it important for a cell to have two copies of DNA before it enters the division phase 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.
When a cell divides how do the new cells get instructions from the original cell?
It gets duplicated. Servylia's answer: The two strands of DNA separate, one going to each new cell. A new strand then forms in each new cell, the exact match for the strand from the original cell, so that they fit together rather like pieces in a jigsaw puzzle. The bases on one strand precisely match the bases on the other so that they now sit in pairs just like in the original DNA molecule: * A with T * G with C This means that the original double helix has turned into two absolutely identical double helixes - and so the DNA of the two new cells is absolutely identical to the DNA of the original cell. As an organism develops, this cell-division mechanism means that all cells will contain exactly the same DNA molecules. Each DNA molecule in turn contains many millions of the organic base pairs described above.
