Humans have species resistance to feline immunodeficiency virus for which of the following reasons?

Human cells do not have the chemical receptors required for attachment by feline immunodeficiency virus.
Feline immunodeficiency virus is a nonpathogenic virus.
Human phagocytes are extremely effective at eliminating feline immunodeficiency virus from the body.
Human cells produce a special type of interferon that protects against feline immunodeficiency virus.

Human cells do not have the chemical receptors required for attachment by feline immunodeficiency virus

Explanation:

Feline immunodeficiency virus is a virus which causes immunodeficiency in the cats worldwide that is they use the cat as a host to replicate themselves by using their DNA replication machinery.

The feline virus does not affect the humans or they cannot affect the humans and this could be accounted to the reason that human body does not have the receptors which allow the cell to surface interaction between the body and the virus. Since a virus does not get attached to the body, therefore, cannot affect the humans.

Thus, the selected option is correct.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
