Science – Genetics

Posted in Science on the 04.02.2012

The term Genetic engineering can be explained as a technique that can be used to identify and modify genes in plants, animals and micro-organisms to produce products such as industrial or medical purposes. By that I mean to use genetic engineering to such spraying plants to improve color or use genetic engineering to create new drugs to solve particular diseases or allergies.

Genetic engineering can also be used to transfer DNA and organisms from one to another to provide completely new properties. Gene technology three important tools are plasmids, enzymes and bacteria. Plasmids are SMALL strafing, round DNA molecules from bacteria. They can be transferred from one bacterium to another that may have new properties. Plasmids are found naturally in many bacteria. One way to produce recombinant molecule is to cut another rDNA and put it together and “paste” it by means of enzymes within the plasmid.

The cells in the DNA molecule is sort of a genteknologer. They have enzymes, that is, for example, saliva, such as copy, cut and paste DNA. The enzymes have a common way to copy DNA and fix the DNA if it is damaged.

For us to work with DNA molecules in the laboratory, for example, we need to clone the DNA molecule, ie to make a copy of the DNA molecule. Cloning of DNA can occur in two ways, the first and easiest way is to let the bacteria do the work for us and the other way to clone the DNA is, using DNA polymerase, a polymerase is an enzyme. We can copy DNA polymerase in a test tube with the polymerase chain reaction.
