A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

Scientists who have described in a new study the step-by-step details of a bacterial defense strategy see the mechanism as a promising platform for development of a new genome-editing method.

Grow bacterial clones, having plasmid DNA of interest Inoculate single clones into a 96-well, 2 mL, square-well plate holding 1.2 mL/well Terrific broth (TB) with suitable antibiotic(s) Grow cells ...

Imported seafood may be spreading colistin-resistant “superbugs” into U.S. kitchens as a new study warns of rising antibiotic ...

Some bacteria already contained a circular piece of DNA, called a plasmid, which carries antibiotic-resistance genes. Those resistant cells (green) pass the plasmid to sensitive cells (red).

An interdisciplinary study reveals a unified model for plasmid distribution in bacterial cell division. November 15, 2022. Cell Biology Microbiology (B&M) Using a combination of biology and ...

Scientists who have described in a new study the step-by-step details of a bacterial defense strategy see the mechanism as a promising platform for development of a new genome-editing method.

Results and discussion. If a good yield from plasmid DNA isolation is to be achieved, it is essential that bacteria cells are optimally grown before the method is run. This study employed a Design ...
