FAR121/4 Microbiology for Pharmacy Lecture bacteriuml Genetics (4 hours) by Dr. Suriani Mohamad References cellular teleph wiz and Molecular Biology Molecular Biology of The mobile phone Principals of Genetics What Is Genetics ? field of honor of heredity or transmission of data from an organism (pargonnt) to its upshot (offspring/children) ? Genetic information is stored in the form of deoxyribonucleic acid (however, in certain viruses, contractable poppycock 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) bacterium genome: chromo any(prenominal) + extra chromosomal DNA molecules ( plasmid DNA DNAs, episomes) Single chromosome: Escherichia coli, Klebsiella sp., mycobacteria sp. etcetera Two chromosomes: Burkholderia sp., Ralston ia sp., Vibrio cholerae. Extra Chromosomal DNA Plasmids: circular repeat stranded DNA molecule that replicates severally (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 tumor in plants. F plas mid (fertility factors), Carries rep and tr! a genes Transmissible or non transmissible plasmids R plasmids (Resistance) fill genes that provides apology to various antibiotics (eg. catR, tetR, kanR) generally 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 patient of to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
