What is the size and shape of bacterial DNA?
DNA is 22 to 36 angstroms wide (2.2 to 2.6 nanometers), and one nucleotide unit is 3.3 Å (0.33 nm) long.Although each individual repeating unit is very small,
Yes! bacteria can produce DNA as it also have genetic material in the form of DNA (plasmids) so as many time bacterial cell divide it produce DNA and intrestingly bacteria are used in many biotechnical process in which forigen DNA is incooperated in bacterial DNA for the production which then is isolated from the bacterial DNA.
DNA gyrase is a bacterial enzyme which introduces supercoils into the bacterial DNA, resulting in a highly condensed 3-dimentional struture. it is also known as Topoisomerase. Quinolones and F/Quinolones inhibit this enzyme and thus interfere with bacterial DNA replication. The enzyme is absent in humans.
Bacterial DNA does not have the introns that make human (and other organisms) DNA so diverse. Many more different sequences can be assembled from human DNA because of the the introns. The exons can be spliced together in different orders so that different proteins can be made. Bacterial DNA is far more compact. A greater % of bacterial DNA is actually expressed partly because they don't have the introns to cut out.
