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.

the team of researchers took a closer look at this plasmid, which consists of only two genes that rather surprisingly only ...

Plasmids are small, circular, double-stranded DNA molecules that move from one cell to another, transferring genetic material without killing the host bacterium. As part of this DNA exchange, plasmids ...

One of these mechanisms involves plasmids, small DNA molecules in bacterial cells, which have their own independent genome and carry antibiotic ... John Innes Centre researchers and partners used a ...

They found that anodic porous alumina (APA) surfaces prepared using electrochemistry in concentrated sulfuric acid had unprecedented resistance to bacterial growth, but did not hamper cell cultures.

For example, bacteria have a rigid cell wall, whereas human cells are surrounded only by a simple membrane. If a pharmaceutical agent targets cell wall construction, only bacterial cells are affected.
