Chapter8 Microbial genetics 8.4 Plasmids 8.5 Genetic Conjugation, Transformation, transduction 8.6 Transposons and Insertion Sequences

Microbial molecular biology and genetics A clone: a population of cells that are derived asexually from a parental cell and are genetically identical. Genome: all the genes present in cell or virus. Central dogma:dna→rna→ protein transcription translation

7.1 An overview of metabolism Metabolism may be divided into two major parts: catabolism and anabolism. Catabolism: larger and more Waste products complex molecules are broken Nutrients Biosynthesis down into smaller, simpler Energy molecules with the release of for growth energy

Related concepts Aspecies: a collection of strains that have a similar G+C composotion and 70% or greater similarity as judged by DNA hybridization experiments. biovars: variant procaryotic strains characterized by biochemical or physiological differences. Morphovars: differ morphologically Serovars: have distinctive antigenic properties
