Question

What is the difference between virus attachment events and virus entry events that occur at the cell surface?

Answer 1

in viral attachment step virons must first attach to the receptors in plasma membranes to enter into the cell

every virus has individual receptors to bind with the hosts

next a part of the protein will cross the memberane can be called as viral entery step were it is the earliest step of viral infection

where it undergoes in 3 different ways

1. Membrane Fusion or Hemifusion State: hear cell membrane will be punctured and undergoes to further connect with the unfolding viral envelope.
2. Viral Penetration: The viral capsid or genome is injected into the host cell's cytoplasm
3. Endocytosis: The host cell takes in the viral particle through the process of endocytosis, essentially engulfing the virus like it would a food particle..

viral attachment is the primary step for the virus to capture the host cells to penetrate into it either by adsorption or attachment

where as virus penetration is the next step to pass into the host cells
