Circular single-stranded DNA (ssDNA) viruses are a diverse group of viruses characterized by their unique circular genomes and ability to infect a wide range of hosts, including animals ...

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.

Prof. Burstein explains, "Plasmids are small, circular, double-stranded DNA molecules classified as 'mobile genetic elements.' Like viruses, plasmids move from one cell to another, but unlike ...

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 ...
