Bacteria divide by splitting in half.
They are unicellular organisms, meaning they are only one cell. There are fundamental differences- a prokaryote is a simple single celled organism that uses different basic machinery for its cellular processes. B.Brett Finlay received his undergraduate and Ph.D.in the mechanisms of bacterial conjucation from the University of Alberta, studying under the world-renown microbiologist, Stan Falkow. He then moved to Vancouver and began his own laboratory where he focuses on Salmonella and E. Coli bacteria. You get to find things that no one else has seen before.
