Complementary DNA (cDNA) is DNA that has been copied from an mRNA through a reverse transcriptase enzyme. cDNA contains a copy of the original DNA sequence that made the mRNA - but without the introns (as these are cut out to create mRNA).
DNA is cut by a special kind of enzymes called restriction enzymes.
It could be cut for many reasons. When undergoing meiosis, DNA is cut to create novel gene arrangements on chromosomes. DNA can also be damaged by mutagens like UV light, and will be cut by certain enzymes to help in the repair on the DNA. In the lab, biologist cut DNA to insert genes, knock out genes, or to ensure that the gene is there. These are just a few reasons, but it is useful to cut DNA both in the lab and in the organism.
DNA is duplicated during the S phase of the cell cycle, prior to cell division. DNA is duplicated to ensure that each new cell receives an exact copy of the genetic information, allowing for the accurate transmission of genetic material to the daughter cells.

Scientists use restriction enzymes to cut out the specific part of DNA they want to copy. These enzymes recognize and cut DNA at specific sequences, allowing researchers to isolate the desired section for replication.
They are called restriction enzymes and there are all sorts depending on the sequence of DNA they are trying to cut

Cut Copy was created in 2001.
Because restriction enzymes recognised site normally are more than one.For example, if an enzyme recognise three Base pair such us AAA and the copy segment of DNA has 5 AAA segment than the enzyme will cut the DNA into 5 picies.
obtain DNA with the desired gene, cut the DNA into pieces, copy the pieces of DNA, identify copies of the desired gene, and transfer the desired gene to the recipient organism. for Plato the answer is A. not B. C. or D.
