Bacterial Book · November with 3, Reads. Honestly, I didn't need this book at all for the class I was taking. I think I read about 15 pages. But the 15 pages were relatively helpful. I later TA'd for the class .

Conjugation Conjugation involves the transfer of genetic material between plasmids via a specialized "Sex Pilus". The proteins of the sex pilus and conjugation machinery are encoded on a specialized plasmid termed the "F Plasmid" F is for Fertility. Recall that Plasmids are small, circular pieces of double stranded DNA that can replicate independent of the bacterial genome within the bacterial cytoplasm.
In a small fraction of cases, the F Plasmid becomes integrated into the bacterial host genome and is subsequently clipped out prior to F Plasmid transfer. Fragments of the bacterial host genome can sometimes be accidentally clipped out along with the F Plasmid and can thus be transfered to other bacteria along with the F Plasmid.
Genetics of Bacterial Diversity
Transposons Transposons are elements of DNA integrated within the bacterial genome which can move to other locations within the same genome. Transposons do this by coding for proteins which clip out the transposon from the bacterial genome and then re-integrate it into another location within the genome.
Transmission of genetic information in most eukaryotic organisms rests on sexual reproduction that allows the generation of genetically variable offspring through the process of gene recombination.
Even though bacteria show an apparent preference for asexual reproduction, they too have evolved mechanisms to trade their genetic material. In fact, bacteria not only could acquire many genes from close relatives, but also from entirely distant members through the process of horizontal gene transfer.
Their success story of long evolutionary existence will stand testimony to these mechanisms. While teaching a course on Microbial Genetics to the post-graduate students at Delhi University, it was realized that a book devoted to bacterial genetics may be very handy to the students, researchers, and teachers alike.
A strong foundation in genetics also helps in comprehending more modern concepts of molecular biology and recombinant DNA technology, always a favorite with the students and researchers.Her major area of research is in genetics of metal-microbe interaction, plant growth promoting characteristics of rhizospheric bacteria, peptide antibiotic production by lactic acid bacteria, and metagenomics.
For example, in a cross of Hfr-donating markers in the order met, arg, leu, we would expect a distribution of fragments such as the one represented here: Note that many more fragments contain the met locus than the arg locus and that the leu locus is present on only one fragment.
Phage can confer key phenotypes on their host, for example converting a non-pathogenic strain into a pathogen, and they play a key role in regulating bacterial populations in all sorts of environments.
Molecular Mechanisms of Quorum Sensing C.
In a cross such as the one just described, one class of potential recombinants requires an additional two crossover events Figure d. Conjugation Srivastava, Sheela Pages The molecular mechanisms involved in these processes were largely unknown. Original Price: Only very recently has the study of bacteriophage genomes become prominent, thereby enabling researchers to understand the mechanisms underlying phage evolution.
