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.
Bacterial DNA â a circular chromosome plus plasmids. The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid.This sits in the cytoplasm of the bacterial cell.In addition to the chromosome, bacteria often contain plasmids â small circular DNA molecules. Bacteria can pick up new plasmids from other bacterial cells (during conjugation) or from the environment.They can also readily lose them â for instance, when a bacterium divides in two, one of the daughter cells might miss out on getting a plasmid.acteria can pick up new plasmids from other bacterial cells (during conjugation) or from the environment.
