1 This single DNA molecule can contain ALL of the genetic information the cell needs. 2  In bacteria, the chromosome is found in a region of the cytoplasm called the nuclear region, but the chromosome is NOT contained within a nucleus. 3  In Eukaryotic chromosomes, there are normally two or more kinds of chromosomes. In prokaryotic organisms (bacteria) there is normally ONE chromosome. 2  It is a single DNA molecule arranged in a circle (no ends). 3  This single DNA molecule can contain ALL of the genetic information the cell needs.
