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.
Almost all plasmids are circular. They contain a small number of genes, which can include genes that make cells resistant to antibiotics. Plasmids are used extensively in cloning DNA. You insert some foreign DNA into the plasmid DNA, and then infect cells with the DNA in a process called transformation.There are several ways to purify plasmids. These methods are often called âminiprepsâ because you are purifying DNA from a small volume of cells.hey contain a small number of genes, which can include genes that make cells resistant to antibiotics.
