Question

Quizplus · Accepted Answer

The host range of a virus is limited by the type of host cell receptors on the cell membrane. The virus must be able to bind to a specific receptor on a host cell in order to enter it and replicate. If the virus cannot bind to receptors on a particular cell type, it will not be able to infect that cell. The other choices (type of nucleic acid, age of host cell, size of host cell) do not limit the host range of a virus.
