Chapter 13, Problem 6
The ability of a virus to infect an organism is regulated by
a. the host species.
b. the type of cells.
c. the availability of an attachment site.
d. cell factors necessary for viral replication.
e. all of the above
Verified step by step guidance1
Understand that viral infection depends on multiple factors related to both the virus and the host organism.
Recognize that the host species is important because viruses often have a limited range of species they can infect due to compatibility with host cell receptors.
Consider the type of cells within the host, as viruses typically infect specific cell types that provide the right environment for replication.
Acknowledge the necessity of an attachment site on the host cell surface, which allows the virus to bind and initiate infection.
Remember that cell factors inside the host cell are required for viral replication, meaning the virus depends on the host's cellular machinery to reproduce.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Host Specificity
Host specificity refers to the range of host species that a virus can infect. This is determined by the compatibility between viral surface proteins and host cell receptors, meaning a virus can only infect species whose cells have the appropriate receptors.

Cell Tropism
Cell tropism is the preference of a virus for infecting specific cell types within a host. This depends on the presence of suitable receptors on the cell surface and the internal environment that supports viral entry and replication.

Viral Attachment and Replication Factors
Successful infection requires the virus to attach to specific sites on the host cell surface and utilize cellular machinery for replication. The availability of attachment sites and necessary intracellular factors determines whether the virus can replicate effectively.
