Chromosomal dna and plasmid dna
WebPlasmids are circular double stranded DNA molecule that are distinct from the cells chromosomal DNA. The structure and function of a bacterial cell is directed by the genetic material contained within the chromosomal … WebPlasmid is a double stranded, circular extra chromosomal DNA of bacterium. It is used in recombinant DNA experiments to clone genes from other organisms and make large quantities of their DNA. Plasmid can be transferred between same species or between different species. Size of plasmids range from 1-1000 kilo base pairs.
