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.
Most of the living bacteria that are known to be parasitic and cause diseases are also found in this kingdom. The three basic morphological types of bacteria are: bacillus (rod shaped), cocci (spherical), and curved/helical.
