Plasmids are small double-stranded DNA pieces of DNA that exist outside the chromosome of the cell in which they are located. Almost all plasmids are circular. They contain a small number of genes, It typically exists as a covalently closed circular piece of double stranded DNA that has the capability of replicating autonomously and it is this property that leads to its isolation and physical recognition. The closed covalent nature of their structure allows them to be separated from chromosomal DNA by either gel electrophoresis or . with fluorescent proteins. Laboratory Introduction.

Part 4: How do we isolate the plasmid DNA from our bacteria . Isolating plasmid DNA. The key is to separate the plasmids from the bacterial chromosome. This is not trivial, since they are both DNA. What is the difference?. Many cloning vectors have been engineered so that. the protein being expressed will be fused to another. protein, called a . tag, which can be used to facilitate. protein purification. Examples of tags include glutathione-.
