9 thoughts on “ Plasmid ”

  1. Plasmid, in microbiology, an extrachromosomal genetic element that occurs in many bacterial strains. Plasmids are circular deoxyribonucleic acid (DNA) molecules that replicate independently of the bacterial chromosome. They are not essential for .
  2. A plasmid is a small, often circular DNA molecule found in bacteria and other cells. Plasmids are separate from the bacterial chromosome and replicate independently of it. They generally carry only a small number of genes, notably some associated with antibiotic resistance. Plasmids may be passed between different bacterial cells.
  3. plasmid [plaz´mid] an extrachromosomal self-replicating structure found in bacterial cells that carries genes for a variety of functions not essential for cell growth. Plasmids consist of cyclic double-stranded DNA molecules, replicating independently of the chromosomes and transmitting through successive cell divisions genes specifying such functions.
  4. Plasmid A is Mb and plasmid B is Mb. These plasmids are larger than the entire genomes of many obligately symbiotic bacteria and even some free-living bacteria. Plasmid A is the typical symbiotic plasmid with nod, nif, and fix genes, whereas plasmid B has genes for exopolysaccharides required in the symbioses of this species.
  5. A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial .
  6. Addgene, the nonprofit plasmid repository, accelerates science by sharing useful plasmid-based research materials, viral preps, and information worldwide.
  7. Plasmid pcDNASARS2-Spike from Dr. Fang Li's lab contains the insert SARS-CoV-2 Spike and is published in Nature. Mar pii: /sy. doi: /sy. This plasmid is available through Addgene.
  8. The ideal plasmid vectors have high copy numbers inside the cell. As such, it ensures high numbers of the target gene for cloning purposes. This also ensures that the gene of interest is increased during genomic division. In addition, the plasmid can have a marker gene as the visual marker to help determine whether cloning was successful.
  9. Plasmid definition, a segment of DNA independent of the chromosomes and capable of replication, occurring in bacteria and yeast: used in recombinant DNA procedures to transfer genetic material from one cell to another. See more.
