Virology Exam 1 What is the ultimate function of the Virion? - correct answer To transmit the genome, which is inside, efficiently and effectively to the host organism. What are some viral properties that are important for survival of the virus in nature? - correct answer 1. Must have protection from chemical agents, physical damage, and enzyme damage. 2. Must contain a capsid so that it can recognize essential receptors that will lead to its replication and recognition with the host cell....
