Answer:
Correct Statments:
- Viruses are not capable of metabolic activity on their own; they must have a host cell to reproduce.
- The genetic material of a virus can be DNA or RNA.
- Viruses can have different shapes.
- Capsids function to surround and protect the nucleic acid core.
- The genomes of viruses are usually smaller than the genomes of bacteria.
Incorrect statments:
- All viruses have both a capsid and an envelope.
- Capsids are adquired from the host cell during replication or release.
- The intracellular state of a virus is called a virion.
Explanation:
This statements allow both to classify the viruses and also to distinguish between virus and bacteria.
