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.

Closed circular mitochondrial DNA molecules which are catenated, or connected like the links in a chain, have been identified in extracts of HeLa cells.

This resistance mechanism relies on plasmids, small circular DNA elements. Antimicrobial resistance poses serious public health issues, with thousands of deaths each year. These infections often occur ...
