In electron micrographs of HSV infection, it can be seen that the intact virus initially reacts with cell surface proteoglycans, then with specific receptors. This is later followed by viral capsids docking with nuclear pores. Afterward, the capsids go from being full to being "empty." Which of the following best fits these observations? A) The viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus. B) Only the genetic material of the virus is involved in the cell's infectivity, and is injected like the genome of a phage. C) The viral capsid mediates entry into the cell, and only the genomic DNA enters the nucleus, where it may or may not replicate. D) The viral envelope is not required for infectivity, since the envelope does not enter the nucleus.

Answer is (A)

Explanation:

An virus that has an external wrapping or envelope it is called as Viral Envelope. A capsid is the protein which is present in outer covering of a virus. A genome is an organism's arrangement of DNA, including the entirety of its qualities. Every genome contains the information of the data expected to assemble and keep up that life form.
