They grow relatively quickly, and most reproduce by binary fission, the production of two identical daughter cells from one mother cell. The DNA within bacterial cells contains a variety of features and signals that influence the diversity of the microbial world. It is one of the cornerstone of molecular genetics. Molecular Cloning Herbert Boyer and Stanley Cohen first demonstrated the complete molecular cloning process in 1973 when they successfully cloned genes from the African clawed frog (Xenopus laevis) into a bacterial plasmid that was then introduced into the bacterial host Escherichia coli. Bacterial genetics are subtly different from eukaryotic genetics, however bacteria still serve as a good model for animal genetic studies. The genetic information for making a pilus is called the F (fertility) factor. The principle of transduction is based on the mechanism of infection of the bacteriophage. Modern Applications of Microbial Genetics. Firstly, bacteria are generally haploid, with one copy of each gene on a single circular chromosome. Conjugation is the technique of transfer of genetic material from one bacteria to another placed in contact. The National Tribune. 1.
