WebThe single circular chromosome of E. coli contains about five million DNA base pairs, only 1/600th the haploid amount of DNA in a human cell. In addition, the E. coli cell may contain small, circular DNA molecules (1,000 to 200,000 base pairs called plasmids, which also carry genetic information. WebIts genetic material consists mostly of one large circle of DNA 4-5 million base pairs (mbp) in length, with small loops of DNA called plasmids, usually ranging from 5,000-10,000 base pairs in length, present in the cytoplasm.
