Viruses Can Attach to Target Cells By

Question

Viruses can attach to target cells by
A)hooks.
B)fibronectin.
C)pili.
D)suckers.
E)envelope spikes.

Accepted Answer

Envelope spikes, also known as viral glycoproteins, are the primary means by which viruses attach to target cells. These spikes bind specifically to receptors on the surface of the host cell, allowing the virus to enter and infect the cell. Hooks, fibronectin, and pili are not typically involved in viral attachment, and suckers are not a recognized mode of attachment for viruses.
