Reproduction

How does E. coli reproduce?

East. coli reproduces by two means: prison cell division , and the transfer of genetic textile through a sex pilus ( conjugation ).

Escherichia coli, when undergoing cellular sectionalisation, is using a ways of asexual reproduction because in that location is no transfer of genetic cloth; the bacterium is merely making an verbal copy of itself (lookout out for the a ttack of the Clones !).  This is the most prevalent form of reproduction for East. coli.  The individual bacterium begins this process by elongation of the cell, followed past almost exact replication of the genome so in that location are 2 identical copies. Mutations and mistakes may happen during genetic replication, merely ordinarily these occur in small numbers and don't take a large effect on the bacterium.  A septum is formed, and the cell equally divides the cellular components and one copy of the parental genome gets placed in each side of the cell.  The cell divides, leaving two copies of the original bacterium called daughter cells .

bacterial cells via a specialized type of fimbriae called sex pili (also known as conjugate fimbriae ).  This is Not sexual reproduction because there is no fusion of gametes present. is more infrequent than cell partitioning, but information technology allows for a means of genetic diversity between bacteria, and the possibility of beneficial adaptations such as antibiotic resistance.
E. coli that comprise an fertility factor (
F+ ) know as a plasmid undergo conjugation past first copying its genome.  This bacterium is chosen the donor .  Information technology then releasing an enzyme that

contains a "mating signal", showing that it is ready for genetic transfer.  This mating enzyme attracts a bacteria that doesn't contain the fertility cistron ( F- ). This bacterium is the recipient .  The donor E. coli bacterium connects the sex pilus to the recipient bacterium, and injects the plasmid.  Once the hair is disconnected, the transfer stops.
