Final answer:
The claim that a virus in its intracellular phase is in a transmittable state is false. A virus is transmittable when new virions are released from the host cell and able to infect new cells.
Step-by-step explanation:
The statement that a virus in an intracellular phase is in a transmittable state is false. When inside a host cell, a virus may enter a latency period, especially if conditions are unfavorable, meaning that it is not actively replicating or being transmitted. During the viral replication cycle, which includes the stages of attachment, penetration, uncoating, replication, assembly, and release, it is specifically at the release stage where new virions are able to infect adjacent cells. This is when the virus is considered to be in a transmittable state, not while it is in the intracellular phase.
