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.

A new study has uncovered how the defense mechanisms of bacteria can be neutralized, facilitating more efficient genetic ...

A new study by Tel Aviv University reveals how bacterial defense mechanisms can be neutralized, enabling the efficient ...

into dangerous bacteria such as Shigella dysenteriae, in a blink. The word “episome” would later be replaced by a synonym, “plasmid.” Scientists now recognize plasmids as a major mechanism ...

The diagram illustrates the process of genetic modification using Agrobacterium tumefaciens. Initially, the agrobacterium cell contains a bacterial chromosome and a Tumor-inducing plasmid (Ti plasmid) ...

She identified genes linked to ‘anti-defense’ systems, which help plasmids bypass bacterial defense barriers. Notably, these genes were consistently located near the DNA cut site—the point where one ...

Bacteria can exchange plasmid DNA through a process known as horizontal genome transfer. The university's team has isolated and analysed 500 strains of bacteria and found significant levels of ...
