Recombinant DNA is widely used in biotechnology, medicine and research. Today, recombinant proteins and other products that result from the use of DNA technology are found in essentially every pharmacy, physician or veterinarian office, medical testing laboratory, and biological research laboratory.
Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...
The DNA band at the correct size should contain the gene, where it can be excised from the gel. [18]: 40–41 Another technique to isolate genes of known sequences involves polymerase chain reaction (PCR). [21] PCR is a powerful tool that can amplify a given sequence, which can then be isolated through gel electrophoresis.

The gene gun has become a common tool for labeling subsets of cells in cultured tissue. In addition to being able to transfect cells with DNA plasmids coding for fluorescent proteins, the gene gun can be adapted to deliver a wide variety of vital dyes to cells.
To use this process as a useful and controllable genetic tool, the two parts of the P element must be separated to prevent uncontrolled transposition. The normal genetic tools are therefore: DNA coding for transposase (or occasionally simply transposase) with no transposase recognition sequences so it cannot insert; and; a "P Plasmid".
The usage of recombinant DNA technology is a process of this work. [1] The process involves creating recombinant DNA molecules through manipulating a DNA sequence. [1] That DNA created is then in contact with a host organism. Cloning is also an example of genetic engineering. [1]
Recombinant DNA (rDNA), or molecular cloning, is the process by which a single gene, or segment of DNA, is isolated and amplified. Recombinant DNA is also known as in vitro recombination. A cloning vector is a DNA molecule that carries foreign DNA into a host cell, where it
