Chromosomes Bacterial chromosome- Almost all of the dna of a typical prokaryote like E coli is contained in a single, large, supercoiled circular DNA molecule, with a minor fraction present in small plasmids Eukaryotic chromosomes- The typical eukaryotic cell genome is divided into several or many chromosomes, each of which contains a single, very large, linear DNa molecule. These DNa molecules are commonly of the order of 10 to 10 bp in length. The number of eukaryotic chromosomes ranges from l(in an Australian ant)to 190(in a species of butterfly). Ploidy- Some eukaryotic cells are highly polyploid, carrying many copies of each chromosomeBacterial chromosome - Almost all of the DNA of a typical prokaryote like E. coli is contained in a single, large, supercoiled circular DNA molecule, with a minor fraction present in small plasmids. Eukaryotic chromosomes - The typical eukaryotic cell's genome is divided into several or many chromosomes, each of which contains a single, very large, linear DNA molecule. These DNA molecules are commonly of the order of 107 to 109 bp in length. The number of eukaryotic chromosomes ranges from 1 (in an Australian ant) to 190 (in a species of butterfly).
