Introduction/32.html">Genetic Engineering techniques make it possible to isolate specific genes and introduce them into the genomes of other organisms to alter their phenotype. First, a Gene is isolated from a donor Cell or synthesized artificially. This gene is then attached to a DNA molecule (a vector) capable of delivering it into a recipient cell. The gene is integrated into the recipient cell's genome and subsequently activated. The acquired information is expressed in the phenotype of the recipient cell through METABOLISM/31.html">Transcription and Translation. Phages, Viruses, Plasmids, and Mitochondrial DNA can serve as vectors.

Genetic engineering Methods are widely used in biotechnology to produce microorganisms capable of synthesizing BIOLOGICALLY ACTIVE SUBSTANCES following gene insertion. For example, this approach allows for the creation of an Escherichia coli strain capable of producing Insulin, a hormone essential for treating patients with Diabetes Mellitus. Genetic engineering can also be employed to correct hereditary Metabolic Disorders.
