Question

QUESTION 4 Procapsid or proviion intermediates in virus assembly are generally rather porous structures for which one or more of the following reasons? Note: points are deducted for incorrect answers There has to be room for scaffolding proteins (if present) to exit along with the genome ?b. This allows the genome to successfully enter the viral intermediate via many different pathways, thereby ensunng that every part e is fully packaged O c. There has to be room for scaffolding proteins (if present) to enter along with the genome. ?d. There has to be room for scaffolding proteins (if present) to enter so the genome can escape O . There has to be room for scaffolding proteins (if present) to exit while the genome enters QUESTION S Which one or more of the following statements accurately describe(s) or define(s) a scaffolding protein? Note: points are deducted for incorrect answers A host protein with an enzymatic role (builds provirions) A host protein with a structural role (builds provirions) A viral protein that can help form nuclei for assemby bA viral protein that maintains the stable structure of the virion A viral protein that transiently stabilizes the formation of a provirion A viral protein that most often forms an external framework for helping build a complete vinion, but which is not part of the virion ?g, Avral proten that most often forns an internal framework for helping build a complete vnon, but which is not part ofthe wron QUESTION 6 In the majority of tailed, dsDNA bacteriophage, genome packaging requires which one or more of the following? Note: points are deducted for incorrect answers ? a. A vrai-encoded ATPase b GTP No additional factors since packaging is a thermodynamically favorable process. dA host-encoded ATPase ADP QUESTION 7 Viruses that package their genome at very high (liquid crystaline) density generally are members of which ?ne of the following dasses of viruses? O b SsDNA viruses ? c. Pleomorphic, nonem eloped viruses Positive sense ssRNA viruses Enveloped viruses O e-dsDNA bactenophage and herpesvrses Of Helical nucleocapsids of negative sense ssRNA viruses
