extrachromosomal element

(redirected from extrachromosomal elements)

plas·mid

(plaz'mid),
A genetic particle physically separate from the chromosome of the host cell (chiefly bacterial) that can function and replicate stably and usually confer some advantage to the host cell; not essential to the cell's basic functioning.
Synonym(s): extrachromosomal element, extrachromosomal genetic element, paragene
