plasmid Definition
plas·mid (plaz′mid)
noun
a small, DNA-containing, self-reproducing cytoplasmic element that exists outside the chromosome, as in some bacteria: because it can alter a hereditary characteristic when introduced into another bacterium, it is used in recombinant DNA technology
Etymology: plasm(a) + -id
plasmid Usage Examples
Converse of object
- call: The bacterium contains a section of DNA called a plasmid in addition to its usual component of DNA.
- have: If you have a plasmid that might be interesting to sequence in this context please contact Christopher Thomas.
- carry: Initial experiments are designed to determine if afferent lymph DC carry plasmid, make GFP and/or take up free GFP from the lymph plasma.
- transform: Then you can try and see if you can transform one plasmid and then make that strain competent and then transform the second plasmid.
Adjective modifier
- bacterial: The third step is to join the new gene into the bacterial plasmid.
- second: Then you can try and see if you can transform one plasmid and then make that strain competent and then transform the second plasmid.
- modified: Place the modified plasmid into a dish containing leaf disks cut from the plant to be modified.

Modifies a noun
- replication: For my 4th year project I will be working with the university genetics department to model certain aspects of plasmid replication.
- DNA: Our research aims to employ specific protein-DNA interactions to generate pure plasmid DNA for use in gene therapy.
- vector: How are plasmid vectors constructed for use in genetic modification?
- transfer: Instead, the researchers had to construct completely new plasmid transfer vectors.
- sequence: No genetic maps were given on the constructs or the plasmids used, nor whether any plasmid sequences are integrated into the transgenic plants.
- construct: Plasmid constructs will be introduced into immortal human and mouse cell lines ( such as HeLa and mouse dermal fibroblasts ) by transfection.
Noun used with modifier
- expression: Gateway technology is very suitable for high-throughput production of expression plasmid of FL cDNA.
- helper: Therefore, the helper plasmid lacking one or the other of the ITS cannot integrate itself into target DNA.
- coli: The only information on the plasmid not blacked out was that it was an E coli plasmid.
- donor: Otherwise those original donor plasmid may interfere with the transformation later.
