Which Feature is Common in a Virus

Question

Which feature is common in a virus?
A) cell wall
B) nucleus
C) capsid
D) plasmid

Accepted Answer

All viruses have a protein coat called a capsid that encloses their genetic material. A cell wall is a feature found only in some types of cells like bacterial cells, while a nucleus is only found in eukaryotic cells. Plasmids are small, circular DNA molecules found outside the chromosome in some bacterial cells.
