Bacteriophage T4 has “early genes” and “late genes.” What is meant by these classifications, and what types of proteins are encoded by each?
Answer to relevant QuestionsDescribe the types of genomes found in bacterial viruses. Give an example of one virus for each type of genome. Why does a one-step growth curve differ in shape from that of a bacterial growth curve? Contrast the enzyme(s) present in the virions of a retrovirus and a positive-strand RNA bacteriophage. Why do they differ if each has plus configuration single-stranded RNA as its genome? Describe the classes of viruses based on their genomic characteristics. For each class, describe how viral mRNA is made and how the viral genome is replicated. Not all proteins are made from the RNA genome of bacteriophage MS2 in the same amounts. Can you explain why? One of the proteins functions very much like a repressor, but it functions at the translational level. Which ...
