Question 8 Which of the following are found in all viruses ? DNA, RNA, ribosomes , cell wall Nucleus , ribosomes , cell wall Oc DNA or RNA and a protein coat Cell membrane and ribosomes

Answer 1

The correct answer is: DNA or RNA and a protein coat.

All viruses contain either DNA or RNA as their genetic material, and they are surrounded by a protective protein coat called a capsid. Viruses do not have ribosomes, a cell wall, or a nucleus, and they lack a cell membrane in the same sense that living cells do.
