Question

note on life cycle of poliovirus​

Answer 1

Explanation:

The replication cycle of poliovirus is initiated by binding to the cell surface receptor CD155 (1). The virion is taken up via endocytosis, and the viral RNA is released (2). Translation of the viral RNA occurs by an IRES-mediated mechanism (3). The polyprotein is cleaved, yielding mature viral proteins (4).
