Question

1. every virus particle contains

o dna
o dna and rna
o ribosomes
o either dna or rna

1. viral capsids are composed of

o protein
o lipids
o carbohydrates
o nucleic acids

1. when present, what is the viral envelope composed of?

o carbohydrates
o proteins and lipids
o nucleic acid
o peptidoglycan

Explanation:

1. Viruses contain either DNA or RNA as their genetic material, not both in the same particle, and do not have ribosomes.
2. Viral capsids are the protein - coat surrounding the viral nucleic acid.
3. The viral envelope, when present, is composed of proteins and lipids, often derived from the host - cell membrane.

Answer:

1. either DNA or RNA
2. protein
3. Proteins and lipids
