Genetic information is stored in the form of deoxyribonucleic acid (however, in certain viruses, genetic framework is stored in the form of RNA, eg. severe acute respiratory syndrome virus, HIV) THE BACTERIAL GENOME GENOME: the complete collection of hereditary information for an single organism. Hereditary information exists in the form of DNA (deoxyribonucleic acid) bacteria genome: chromo round + extra chromosomal DNA molecules ( plasmid DNA DNAs, episomes) Single chromosome: Escherichia coli, Klebsiella sp., mycobacteria sp. etcetera Two chromosomes: Burkholderia sp., Ralstonia sp., Vibrio cholerae. Extra Chromosomal DNA Plasmids: circular repeat stranded DNA molecule that replicates respectively (autonomous replication). May take over one or to a greater extent (non-essential) genes, smaller than the bacterial chromosome. normally expresses genes that allows the bacterium to adapt to a certain situation.

Most plasmids are classified by some recognizable functions that they serve in a bacterium, among them: a) F plasmid (fertility factors), b) R plasmids (Resistance) c) Virulence plasmids d) Bacteriocins e) Ti (Tumor-inducing) plasmids slew cause tumor in plants. F plasmid (fertility facto rs), Carries rep and tra genes Transmissib! le or non transmissible plasmids R plasmids (Resistance) fill genes that provides apology to various antibiotics (eg. catR, tetR, kanR) largely contains two components: a safeguard transfer factor (RTF) & one or more resistance (R) genes. RTF mediates transfer of genetic material via conjugation & therefore can transfer resistance to some other organism emergence of bacterial populations that are highly patient of to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
