The Primary Factor Determining the Life Cycle of an Animal

Question

The primary factor determining the life cycle of an animal virus is the physical form of the
A) envelope.
B) capsid.
C) genome.
D) receptor.
E) burst.

Accepted Answer

The physical form of the genome is the primary factor determining the life cycle of an animal virus. This is because the genome contains all the genetic information necessary for the virus to replicate and produce more virus particles. The genome can be either RNA or DNA, single or double-stranded, linear or circular, and can have different sizes and structures. The other factors listed (envelope, capsid, receptor, burst) are important for virus entry, assembly, and release, but they do not determine the life cycle per se.
