The only way in which plasmids can be a location for functioning essential genes is if chromosomal genes degrade faster than plasmid genes. Clipboard, Search History, and several other advanced features are temporarily unavailable. Plasmids are small circular DNA molecules found in bacteria that replicate separately from chromosomes. Spacer acquisition is affected by active viral DNA replication in Sulfolobus species whereas the DNA breaks formation at replication forks causes the process to be stimulated [35]. Like so many genetic technologies used today, recombinant DNA technology had its origins in the late 1960s and early 1970s. DNA from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times. Viral gene therapy is one of the leading and important therapies for head and neck cancer. Plasmid DNA was key to the development of biologic drug manufacturing. Nicholson J. K., Holmes E., Wilson I.
