Publisher Summary The explosion of information in modern cell biology has in many cases
been fostered by the use of viruses as experimental paradigms Subjects as wide ranging as
RNA splicing, DNA replication, on cogenes, cell polarity, and membrane protein
biosynthesis have all taken advantage of the experimental manipulability, high signal-to-
noise ratio, and defined components of virus systems. The usefulness of viruses is similarly
apparent from the studies of the entry pathway of enveloped animal viruses into host cells; …
