Webplasmids are small, circular, double-stranded DNA molecules separate from a cell's chromosomal DNA. They are typically found in bacterial cells, but also can be found in some eukaryotes. The genes contained in plasmids give bacteria genetic advantages, like antibiotic resistance. Web2. A miniprep procedure involves purifying the plasmid DNA from the bacterial culture. Briefly describe the three major steps of this process. Horizontal gene transfer is the mechanisms that plays an important role in transfer of antibiotic resistance gene of bacterium to its progeny.it occurs through three main mechanisms which are …
