Question
Viruses use the host's machinery to make copies of themselves.However, some human viruses require a type of replication thathumans do not normally do. For example, humans normally do not havethe ability to convert RNA into DNA. How can these types of virusesinfect humans, when human cells cannot perform a particular rolethat the virus requires?A) the virus infects only those cells and species that can performall the replication roles necessary.
B) Viruses can stay in a quiescent state until the host cellevolves this ability.
C) the virus has in it own genome the code for any specializedenzymes that the host does not have.
D) The virus causes mutations in the human cells, resulting in theformation of new enzymes that are capable of performing theseroles.
E) All of the above have been frequently observed
If a viral host cell has a mutation that interferes with theaddition of carbohydrates to proteins in the Golgi, which of thefollowing could likely result?
A) The viral capsid proteins will not be glycosylated and may notarrive at the host plasma membrane.
B) The viral core proteins will not be glycosylated and may notarrive at the host plasma membrane.
C) The viral envelope proteins will not be glycosylated and may notarrive at the host plasma membrane.
D) None of the above will happen.
Pleaseeee help!!!!
Explanation / Answer
for the second question you need to know what rolescarbohydrates have on proteins (mostly cell signaling) and wherethese occur on viruses (the envelope) so the answer is also C
