1 mm long DNA molecule is so \u201cpacked\u201d that it can easily be
accomodated by the much smaller recipient cell (2\u20143 x 1\u20141.5 \u03bcm).
DNA-molecule is structured in domains, some of them transcribing, others
\u2014 non-transcribing. The replication starts at a defined spot called origin<\/strong>
(oriC) and stops at another called terminus<\/strong> (terC), being attached to the
cytoplasmic membrane. The very site where at the given moment the act
of replication is taking place (the so-called replication fork<\/strong>) is also
attached to the cytoplasmic membrane. The mode of replication of the
circular bacterial chromosome is shown in Figure 2\u201318. The causes for
the uneven distribution of the genes in the bacterial chromosome, the
presence of plasmids, mobile elements and transpozons and their role in
the bacterial genome are treated in detail in Prozorov\u2019s review (1989).<\/p>\n\n\n\n
