What causes the viral plaques that appear on a bacterial lawn to stop growing larger?
Answer to relevant QuestionsThe promoters on genes encoding early proteins in viruses like T4 have a different sequence than the promoters on genes encoding late proteins in the same virus. Explain how this benefits the virus. Rabies virus and poliovirus both have single-stranded RNA genomes, but only in poliovirus can the genome be translated directly. Explain. How might viruses help explain the differences observed in the DNA replication machinery of cells of the three domains? Replication of both strands of DNA in adenoviruses occurs in a continuous (leading) fashion. How can this happen without violating the rule that DNA synthesis always occurs in a 5′ S 3′ direction? What are silent mutations? From your knowledge of the genetic code, why do you think most silent mutations affect the third position in a codon?
