Microbial genetics
the study of the mechanisms of heritable information in microorganisms, including bacteria, archaea, viruses and some protozoa and fung
Bacterial chromosomes
the genophore or nucleoid carries genetic information (DNA) carried from past generations
Bacterial plasmid
small extra-chromosomal DNA contain some genes such as antibiotic resistance obtained through reco
Bacterial pilus
important for bacterial gene transfers
Fertility plasmids
initiates bacterial conjugation
Resistance plasmids
genes that code for antibiotic resistance or poisons
Virulence plasmid
turns the bacteria into a pathogen
Agrobacterium tumefaciens
virulence plasmid examples
Metabolism plasmid
enables digestion of unusual substances like petroleum
Transformation plasmid
is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment.
Conjugation
the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection (sex pilus) between two cells
Transduction
he process by which foreign DNA is transferred from one bacterium to another by a virus or viral vector
