Plasmids are extra chromosomal, double stranded, circular DNA molecules present in bacteria. Different kinds of bacterial plasmids based on encoded genes (their roles). F-plasmids (fertility factor or sex factors): Bacterial cells with F plasmids are called F+ cells and acts as donor cells or +strain during bacterial conjugation.
Background Information. In order to use your Addgene plasmid, you will need to isolate plasmid DNA from the bacterial cells. To do this, you will lyse the host bacterial cells and separate the proteins, RNA and chromosomal DNA from the plasmid DNA.This procedure is generally referred to as a mini-prep.ackground Information.
