The life cycle of all viruses includes (select the one that is true):
- new viral particles exit the host cell by budding
- viral proteins are synthesized
- negative strand RNA is synthesized
- viruses make ribosomes
Homework Answers
True-new viral particles exit host the host cell by budding.
Explaination:When this occurs, the phage is latent, and the viral DNA is called a prophage. ... Once inside the host cell, the virus loses its envelope and capsid. The viralnucleic acid, now free of its covering, proceeds with biosynthesis. Newly assembled viral particles are released not vial cell lysis, but rather bybudding.
