You Have Extracted Total Protein from a Mutant Virus That

You have extracted total protein from a mutant virus that lacks any a specific enzyme activity, and discover that the extract contains several very large proteins. You compare this to a similar extract taken from a wild-type population of the same species and discover there are no very large proteins, but you do observe additional smaller peptides. How can you explain this result?

A) Polyproteins are evident in the mutant extract.
B) The mutant lacks the ability to hydrolyse the long proteins.
C) The w/t virus was able to produce protein degrading enzymes.
D) A viral encoded protease was functional in the w/t population but not in the mutant.
E) All the options listed here are correct.
