Plasmid is a DNA molecule that is separate from, and can replicate independently of, the chromosomal DNA. They are double stranded and, in many cases, circular. Plasmids usually occur naturally in bacteria, but are sometimes found in eukaryotic organisms .
Plasmids are often used to purify a specific sequence, since they can easily be purified away from the rest of the genome. For their use as vectors, and for molecular cloning, plasmids often need to be isolated. http://www.bio-animations.com/2010/11/plasmid-dna-extraction.html Cheers, Julian Thomas -- Know more about Health, Wealth and Fitness http://unicityin.com --- You received this message because you are subscribed to the Google Groups "Biofriend" group.
