Genetic Engineering

Genetic Engineering

Bioengineering, or genetic engineering is an altering of genes in a particular
species for a particular outcome. It involves taking genes from their normal
location in one organism and either transferring them elsewhere or putting them
back into the original organism in different combinations. Most biomolecules
exist in low concentrations and as complex, mixed populations which it is not
possible to work efficiently. This problem was solved in 1970 using a bug,
Escherichia coli, a normally innocuous commensal occupant of the human gut. By
inserting a piece of DNA of interest into a vector molecule, a molecule with a
bacterial origin of replication, when the whole recombinant construction is
introduced into a bacterial colonies all derived from a single original cell
bearing the recombinant vector, in a short time a large amount of DNA of
interest is produced. This can be purified from contaminating bacterial DNA
easily and the resulting product is said to have been "cloned".

So far, scientists have used genetic engineering to produce, for example: -
improve vaccines against animal diseases such as footrot and pig scours; - pure
human products such as insulin, and human growth hormone in commercial
quantities; - existing antibiotics by more...
