plasmid

  • /ˈplæzmɪd/

Rhymes with -æzmɪd

Where it comes from

From plasma + -id, coined by American molecular biologist Joshua Lederberg in 1952.

noun plasmids

  1. A loop of double-stranded DNA that is separate from — and replicates independently of — the chromosomes; such loops are most commonly found in bacteria, but they are also sometimes found in archaeans and eukaryotic cells, and they are used in genetic engineering as a vector for gene transfer. These discussions have left a plethora of terms adrift: pangenes, bioblasts, plasmagenes, plastogenes, chondriogenes, cytogenes and proviruses, which have lost their original utility owing to the accretion of vague or contradictory connotations. At the risk of adding to this list, I propose plasmid
