Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates).

Reproduction versus s*x in Bacteria
In bacteria reproduction and s*x are
two distinct processes.
Bacterial reproduction and s*x are two
separate processes. Bacteria reproduce by
a process called binary fission. During
binary fission, the DNA is replicated and
the cell separates. Each daughter cell
receives a complete genome. This process
represents as*xual reproduction, as no
exchange or reassortment of genetic
information takes place.
During s*xual reproduction, genes are
reshuffled to increase genetic diversity.
Gene transfer in eukaryotes occurs when
two germ line cells from parents merge to
form a zygote. The zygote contains equal
amounts of DNA from both parents. Gene
transfer in bacteria is a one-way street in
that a donor cell gives DNA to a recipient
cell, but not vice versa.
Gene transfer between bacteria may
occur by uptake of unprotected DNA,
movement of DNA in virus particles,
or cell-to-cell DNA transfer.
Bacterial gene transfer occurs by one of
three mechanisms: transformation,
transduction, and conjugation.
Transformation is the uptake of naked
DNA from the environment. Transduction
occurs via a bacteriophage. The
bacteriophage acquires host cell genetic
information during packaging and
transfers this material to a new host cell
during infection. Conjugation is the
movement of genetic information from
cell-to-cell.
DNA that enters a bacterial cell may
survive on its own if it is a complete
replicon. Otherwise, it will be
degraded unless it is recombined into
the host chromosome.
Incoming DNA for a bacterial cell faces
three possible fates. First, the DNA may
enter the cell and survive as a replicon,
which means it is able to replicate
independent of the host cell’s
chromosome, and therefore must possess
an origin of replication. Second, the
incoming DNA may be completely
degraded. Third, some of the incoming
DNA may be recombined into the host
chromosome, while the rest is degraded.
Recombination usually only occurs
between DNA molecules that share
homology.
