Is a branch of genetics that focuses on the study of DNA, but in order handling. In other words, genetic manipulation of organisms with a predetermined purpose.At this point it will deepen the knowledge on the methods f gene manipulation. The purpose with which they perform such manipulations ill be discussed further when analyzing the scope of this science.
As noted, the IG is the manipulation of DNA. In this very important process called restriction enzymes, produced by various bacteria. These enzymes have the ability tom recognize a particular sequence of nucleotides and remove the rest of the chain. This sequence, called estriction Fragment Length Polymophism or RLPM, can be repositioned with the help of another class of enzymes known as ligases. Similarly, the restriction enzyme becomes a"scissors DNA, and ligase in the" glue. " Therefore, it is possible to remove a
main chain gene and instead put another.
Vectors.
In the process of handling are also important vectors, parts of DNA that can be independently self-replicating DNA of host cells where they grow. These vectors allow for multiple copies of a specific piece of DNA, which provides a large amount of reliable material with which to work. The process of transforming a portion of DNA in a vector is called cloning. But the concept of cloning that "flows" and is on everyone's lips is broader: it is "manufactured" by natural or artificial, genetically identical individuals.
DNA polymerase.
Another method for the production of newly discovered DNA replication is the use of the polymerase enzyme. This method, which consists of a real chain reaction, is faster, easier to perform and economical delivery technique.
