True
Co
orrrec
ct! False
False. Viruses are neither eukaryotic nor prokaryotic.
Question 2 pts
Describe the two basic components of a virus.
Your Answer:
Two basic components of a virus the genomic material comprosed of either DNA or RNA and a capsid, which
is the membrane or protective coat that contains the genetic material
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.
Question 3 pts
The surrounds the capsid of some viruses.
Your Answer:
Capsid
