Genetic information is stored in the form of deoxyribonucleic acid (however, in certain viruses, inherited cloth 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 individualistic organism. Hereditary information exists in the form of DNA (deoxyribonucleic acid) bacteria genome: chromo well-nigh + extra chromosomal DNA molecules ( plasmid DNA DNAs, episomes) Single chromosome: Escherichia coli, Klebsiella sp., mycobacterium sp. etcetera Two chromosomes: Burkholderia sp., R alstonia sp., Vibrio cholerae. Extra Chromosomal DNA Plasmids: circular repeat stranded DNA molecule that replicates individually (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 an! d 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 conjugation & therefore can transfer resistance to other organism emergence of bacterial populations that are highly insubordinate to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
