plasmid Definition

plas·mid (plazmid)

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.
  • single: Along with cross resistance to aminoglycoside antibiotics, pathogenic bacteria frequently develop multiple drug resistance transmitted on a single plasmid.
  • large: Robert is studying the role of a large native plasmid in pathogenicity of P.
  • puc18: Both pUC18 plasmid and transgenic maize DNA were used in the experiments.

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.
