An important mechanism of transferring antibiotic resistance genes (args) among bacteria are temperate bacteriophages (prophages), Viruses that can incorporate their own genetic material into the bacterial chromosome
, Thereby providing their bacterial host (which is now called a lysogen) with additional genes, Such as args.
Only the insertion sequence remains in the bacterial chromosome
Papers describe the latest work in areas such as collagen secretion pathways, bacterial chromosome
organization, ion channels in development and cancer, and genetics of gonadal stem cell removal.
A spindle-like apparatus guides bacterial chromosome
Conclusion: A high prevalence of MTZ resistance was found in the region and bacterial chromosome
mutations in the rdxA and frxA gene still contribute to the high-level MTZ resistance.
The BGI researchers found that the Shiga-toxin-encoding genes, responsible for most of the pathogenicity of the disease, were likely encoded by a viral prophage that integrated in the bacterial chromosome
XerC and XerD normally serve to resolve circular bacterial chromosome
dimers generated by RecA mediated homologous recombination by adding a crossover at a specific 28 bp site dif on the chromosome (16).
Other technologies rely on either integrating the synthetic gene(s) into the bacterial chromosome
or using antibiotics and antibiotic resistance genes to amplify plasmids containing the new genes.
They added yeast DNA, including a centromere, and then inserted this doctored bacterial chromosome
into yeast, in which it replicated and was also susceptible to further engineering.
The pilus (type IV) genes responsible for these processes are all located in the bacterial chromosome
and DNA sequencing revealed the presence of three open reading frames designated pilB, pilC, and pilD that encode proteins of 62, 38 and 32 KDa, respectively .
