Question

How are viruses able to attach to the surface of the cell and invade the cell?

Answer 1

Answer:

In viruses with a viral envelope, viral receptors attach to the receptors on the surface of the cell and secondary receptors may be present to initiate the puncture of the membrane or fusion with the host cell. Following attachment, the viral envelope fuses with the host cell membrane, causing the virus to enter.

Answer 2

Answer:

Hey mate...

good evening!

here is your answer;

A virus attack to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via

glycoproteins abended in the viral envelope. the specificity of this interaction determines the host- and the cells within the host- that can be infected by a particular virus.

secondary receptors may be present to initiate the puncture of the membrane of fusion with the host cell. Following attachment, the viral envelope fuses with the host cell membrane, causing the virus to enter.

I hope it helps you....
