Question

Which of the following is not true regarding viruses?

• A. They can be cultured in artificial media lacking living cells
• B. They do not have a protein synthesizing machinery of their own
• C. They may contain RNA as the genetic material
• D. They can be crystallized and stored

Answer 1

The correct option is A They can be cultured in artificial media lacking living cells

Viruses need living cells or hosts to multiply. So, they cannot grow by themselves in media without living cells. They contain DNA or RNA as the genetic material. They do not have a protein synthesizing machinery of their own. They can be crystallized and stored.
