DNA Cloning – Produces copies of genes or segments of DNA
DNA cloning is the transfer of a DNA fragment of one organism to a self-replicating genetic element such as a bacterial plasmid. The DNA fragment can be propagated in a foreign host cell. This technology has been around for about 30 years and is commonly used in molecular biology. Gene cloning produces copies of genes or segments of DNA.
Some uses of this technology include:
- Isolation of a particular gene, part of a gene or region of a genome
- Production of a desired RNA or protein molecule in large quantities
- Increased production efficiency for commercially made enzymes and drugs
- Modification of existing organisms so that they show a trait that was not previously encoded in the genome.
