Question

When a non-enveloped animal virus adsorbs to the host cell with its protein spikes, the virions are taken into the cell by the process of Group of answer choices production. budding. fusion. penetration. endocytosis.

Answer 1

The correct answer is: Endocytosis.

Step-by-step explanation:

• Endocytosis can be defined as the process by which foreign components or molecules present in the external environment or exterior of the cell are transferred to the cell interior.
• This happens by the invagination of the plasma membrane of the cell towards the cell interior forming an incomplete vesicle-like structure.
• The foreign components or molecules localize inside this vesicle-like structure.
• This structure then buds or pinches off inside the cell forming a complete vesicle containing the foreign components or molecules.
• When the non-enveloped animal virus adsorbs to the surface of the host animal cell with its protein spikes, it signals the plasma membrane of the cell to undergo the process of invagination or endocytosis. Hence, by this way the virions are internalized into the cell.
