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 vecto…
