26. (4) Viruses can shut down host cell translation (globally) and recruit the ribosomes to their own RNAs using a separate, specific method. One way in which they shut down host cell translation is by altering one of the translation factors, eIF4E, rendering it non-functional (in a manner that prevents it from interacting with other partners). Given this information, which step in translation is blocked? Explain in detail how this would inhibit translation?.
