Bacteria can reproduce sexually, but not true sexual reproducers; there is a small transfer of DNA from one bacterium to another unidirectional, NOT exchange NOT entire stand of DNA Sex pili used to form a conjugated bridge for the transfer of information; these pili have no other purpose but to link the donor and recipient cells Only small number of genes are transferred, most of the genes are chopped up and recycled Information can also be transferred through plasmids, little snippets of circular extra chromosomal plasmids.

Unformatted text preview: These are found when a bacteria bursts and the genetic information is spread out into the environment. These plasmids are more often than not complete and this information usually gives a genetic advantage to the organism, plasmids are also self-replicating. If sequence of a gene is known it can be inserted into a bacterium through a plasmid, the protein can then be expressed in the bacteria, example insulin. It is more economical to collect recombinant insulin that it is to collect it from the pancreas of sheep....
