Which of the following describes the last step in the maturation of the picornavirus capsid?

Question

Quizplus · Accepted Answer

The last step in the maturation of the picornavirus capsid is cleavage of VP0 into VP2 and VP4. This cleavage results in the separation of the capsid proteins and the formation of the mature virion. Assembly of the 5S protomer, packaging of the viral genome, and assembly of the 14S pentamer are earlier steps in the maturation process. Cleavage of P1 polyprotein into VP0, VP1 and VP3 occurs before the maturation process begins.
