FAR121/4 Microbiology for Pharmacy Lecture bacteriuml Genetics (4 hours) by Dr. Suriani Mohamad References cellular teleph unrivaled and Molecular Biology Molecular Biology of The cellular phone Principals of Genetics What Is Genetics ? field of honor of heredity or transmission of info from an organism (pargonnt) to its upshot (offspring/children) ? Genetic information is stored in the form of desoxyribonucleic acid (however, in certain viruses, hereditary bodily 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) bacterium genome: chromo rough + extra chromosomal DNA molecules ( plasmid DNAs, episomes) Single chromosome: Escherichia coli, Klebsiella sp., mycobacteria sp. etcetera Two chromosomes: Burkholderia sp., Ralstonia sp., Vibrio choler ae. Extra Chromosomal DNA Plasmids: circular repeat stranded DNA molecule that replicates singly (autonomous replication). May take over one or more(prenominal) (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 neoplasm in plants. F plasmid (fertility factor s), Carries rep and tra genes Transmissibl! e 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 another(prenominal) organism emergence of bacterial populations that are highly kind to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
