What method is not used for the release of animal viruses?

Animal viruses can employ several methods to exit the host cell and spread to new cells. Budding, lysis, and exocytosis are all common processes for viral release.

Budding is a process where the virus acquires its envelope from the host cell membrane as it exits. This method allows the virus to leave the cell without necessarily killing it immediately, thereby providing a sustained release of viral particles.

Lysis involves the breakdown of the host cell, leading to the release of viral particles into the surrounding environment. This method typically results in cell death and is a more aggressive way for viruses to disseminate.

Exocytosis is another way viruses can be released from the host cells, where viral particles are transported in vesicles that fuse with the cell membrane, releasing the viruses outside the cell. This process also allows for the maintenance of the host cell until a later stage, unlike lysis.

Injection, however, is not a method used for the release of animal viruses. While certain types of viruses, such as bacteriophages, do inject their genetic material into host cells, this action is not related to how viruses exit cells. In the case of animal viruses, the focus is on methods that involve the viral particles exiting the cells rather than injecting
