A limiting factor for viral infection is

Question

Quizplus · Accepted Answer

The presence of specific receptor molecules on the host cell determines whether a virus is able to enter and infect the cell. If the host cell does not have the necessary receptor molecules, the virus will not be able to infect it. Therefore, the presence of these specific receptor molecules is a limiting factor for viral infection. Internal metabolic temperature, nutrition, and cell cycle stage may all affect the ability of the virus to replicate once it has entered the cell, but they are not limiting factors for initial infection.
