True or False. Because the genome is contained within an enclosed space (much like the nucleus of a cell), viruses are classified as eukaryotic.
True
False
False. Viruses are neither eukaryotic nor prokaryotic.
Describe the two basic components of a virus.
Your Answer:
The two basic components of a virus are the genomic materia and the viral capsid. The genomic material contains DNA and RNA. The viral capsid is a membrane-like shell that protects the genome.A virus has (1) genomic material comprised of either DNA or RNA and (2) a capsid, a membrane-like protective structure that contains the genetic material, similar to the nucleus of a eukaryotic cell.
