Answer:
The life cycle stage of an animal virus during which a mature capsid forms around copies of the viral rna genome is called excision.
Explanation:
Animal viruses need to infect a host in order to achieve their reproduction and subsequent survival. When the process of producing new phages occurs, they need to leave the host cell and infect other cells. This situation occurs because a process called excision is carried out. In this process, what happens is that the genetic material, in this case the RNA, is packaged in a wrap called a capsid and thus can leave the cell with a protective barrier that will allow it to infect a new host.
