Science / Genetics / Plasmid: Autonomously replicating extra-chromosomal circular dna molecules, distinct from the normal bacterial genome and nonessential for cell survival under nonselective conditions. Some plasmids are capable of integrating into the host genome. A number of artificially constructed plasmids are used as cloning vectors.
Health / Disease / R-Plasmid: A plasmid carrying genes controlling resistance to various drugs. MORE
Science / Biology / Plasmids: Self-replicating, circular DNA molecules found in bacterial cells; often used as vectors in recombinant DNA technology. Small circles of double-stranded DNA found in some bacteria. Plasmids can carry MORE
