Bacteria & Virus Overview. Interesting stuff!. We live with bacteria and viruses constantly, but most people don’t know much about them.. In this chapter we learn both the good and bad of each.  . Bacteria form a large group of parasitic, saprophytic, and free-living microorganism .  . 1. Bacterial cell wall (protects against osmotic damage).  . Bacterial cell is prokaryotic.

Two theories:. 1. . Infolding theory. Lack a nucleus. DNA is naked, a single loop not bound in a chromosome. May contain plasmids (small circular fragments of DNA). Have ribosomes, but no other organelles.. DNA present as a long circular molecule..
