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.
Two - the leading strand and the lagging strand.
CCAATTG
It is a copy of the Dna original strand.
The result of variations DNA copying is that the DNA copies generated will be similar but not identical to the original
mRNA copies the information.Process is called transcription.

The original strands provide a template for making new strands.

A virus is a small strand of DNA or RNA that copies itself.
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.
mRNA copies the information.Process is called transcription.
semiconservative replication - original DNA double strand will unwind into 2 strands, so one original strand will serve as a template for synthesizing a new complementary strand , thus forming a new DNA (one with old strand and one with a new strand)
No. All strands can be replicated, just depends on where the enzyme decides to land and unzip it. Anyways, all DNA molecules would be adequate templates since they are all identical copies of each other.
DNA replication is semi-conservative. This means that each new DNA molecule has one original strand of DNA and one new strand of DNA.
It must be the mirror image of the original half strand. (and the other strand, which is the mirror of the first is making the mirror of the mirror ... the original !)
