Genetic information is stored in the form of desoxyribonucleic acid (however, in certain viruses, transmitted satisfying 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 laissez-faire(a) organism. Hereditary information exists in the form of DNA (deoxyribonucleic acid) bacteria genome: chromo more or less + extra chromosomal DNA molecules ( plasmid DNA DNAs, episomes) Single chromosome: Escherichia coli, Klebsiella sp., mycobacteria sp. etcetera Two chromosomes: Burkholderia sp., R alstonia sp., Vibrio cholerae. Extra Chromosomal DNA Plasmids: circular repeat stranded DNA molecule that replicates respectively (autonomous replication). May take over one or much (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 plasm id (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) by and large 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 rebarbative to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
