The Genetics of Viruses and Bacteria

The Genetics of Viruses and Bacteria. By: Stefanie Vorleiter. Molecular biology was started by the study of viruses and bacteria. E. Coli and other microbes are model systems. P rovides great support that genes are made of DNA.

BACTERIAL TOXINS {ST1}

BACTERIAL TOXINS {ST1}. BY RANJEET RAMAN. Major two classes of bacterial toxins are endotoxins and exotoxins . Endotoxins are intracellular and cell-associated, and are active only when cells lyse. They are ?part of Gram- bacteria, and the classic endotoxins is a lipopolysaccharide.
