Genetic information is stored in the form of deoxyribonucleic acid (however, in certain viruses, inherited visible 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 individual organism. Hereditary information exists in the form of DNA (deoxyribonucleic acid) bacterium genome: chromo or so + extra chromosomal DNA molecules ( plasmid DNA DNAs, episomes) Single chromosome: Escherichia coli, Klebsiella sp., mycobacteria sp. etcetera Two chromosomes: Burkholderia sp., Ralstonia sp., Vi brio cholerae. Extra Chromosomal DNA Plasmids: circular repeat stranded DNA molecule that replicates on an individual basis (autonomous replication). May take over one or more than (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 tumour in plants. F plasmid (fertility factors), Carries rep and tra genes Transmissible or non transmissible plasmids R plasmids (Resistance) fill genes that provides apology to various antibiotics (eg. catR, tetR, kanR) for the most part contains two components: a safeguard transfer factor (RTF) & one or more resistance (R) genes. RTF mediates transfer of genetic material via conjugati on & therefore can transfer resistance to an! other(prenominal) organism emergence of bacterial populations that are highly yucky to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
