Question

find the morphology for poliovirus

Answer 1

Answer:

Morphology of poliovirus-

Poliovirus is a virus from the genus Enterovirus and from the family Picornaviridae.
It is a spherical and enveloped virus. It has a diameter of 25-30 nm. The capsid of the virus is composed of 60 protomers which are made up of 4 virion proteins namely VP1, VP2, VP3, and VP4 which are arranged in icosahedral symmetry.
The VP1, VP2, and VP3 together form the outer face of the viral capsid and the VP4 forms the capsid wall inside.
These virion proteins are intermixed in such a way that it creates loops that serve as an attachment site for corresponding antibodies.
The VP1 coat protein faces outside and creates a star-shaped flat surface or "mesa". Surrounding that is a "deep canyon" where the receptors bind. VP1 has antigenic sites for specific neutralizing antibodies for each serotype.

The capsid morphology is illustrated in a diagram below-
