Question

A vertically transmitted endogenous retrovirus is:

B)Rhinovirus
C)Avian influenza virus
D)Ebola virus
E)None of the choices is correct

Accepted Answer

A vertically transmitted endogenous retrovirus is a retrovirus that has become a permanent part of the host genome and is transmitted from parent to offspring through the germ cells. Mouse mammary tumor virus is an example of a vertically transmitted endogenous retrovirus, as it is found in the genome of mice and is transmitted from mother to offspring through the milk. Rhinovirus, avian influenza virus, and Ebola virus are not retroviruses, and are not known to be vertically transmitted in this manner.
