I need help with this one I just need a paragraph to get me started.
Antibiotics have made it possible for humans to fight infectious disease. When considering how antibiotics control bacterial pathogens we find that the mechanism is the prevention of some necessary physiological process of the bacterium. For example, strepto
The promoters for mRNA encoding early proteins in viruses like T4 have a different sequence than the promoters for mRNA encoding late proteins in the same virus. Explain the viral strategy behind this and how promoter modification occurs.
