Biology Notes on Genetics

A bacterium is a single, prokaryotic cell. It has a cell wall but lacks a nucleus and membrane - bound organelles. A bacterium's single DNA molecule is not coiled around proteins to form chromosomes. Instead, its face of the plasma membrane like a rope attached to the inner wall of a tent. First the DNA is copied, and then the cell splits.
Before a bacterium can divide it must have two copies of its DNA so that each of the new two cells will have a complete copy of the genetic information of that bacterium. …
