Rating Newest Oldest. Best Answer: No, plasmids are not necessary to allow bacteira to survive .Plasmids are typically not strictly for survival and are only beneficial under certain conditions. The DNA necessary for bacterial life is usually in the chromosomal DNA. The plasmid DNA may confer benefits but the function of most plasmid DNA is currently unknown. Scientists have selected for plasmid free bacteria, and plasmid-free strains, especially E. coli, are available commercially.
Types of Plasmids. The combination of elements often determines the type of plasmid. Below are some common plasmid types: 1  Cloning Plasmids-Used to facilitate the cloning of DNA fragments. 2  Cloning vectors tend to be very simple, often containing only a bacterial resistance gene, origin and MCS.3  They are small and optimized to help in the initial cloning of a DNA fragment.ypes of Plasmids.
