Host range is limited by

Question

Quizplus · Accepted Answer

The type of host cell receptors on the cell membrane determines the range of hosts a virus can infect. The virus needs to be able to bind to specific receptors on the surface of the host cell in order to enter and infect it. Therefore, if the virus cannot recognize and bind to a receptor on a potential host cell, it cannot infect that host. The type of nucleic acid in the virus and the size of the host cell do not limit host range, and the age of the host cell is not relevant to host range.
