Question

Which of the following is a characteristic feature of viruses?

• A. They have their own protein synthesizing machinery
• B. They can live independently
• C. They undergo mutation
• D. They undergo meiosis

Answer 1

The correct option is C They undergo mutation

Viruses are made of nucleic acids (genetic material) and proteins. The genetic material is capable of undergoing changes called mutations. Viruses lack a cellular structure. So, they lack their own protein synthesising machinery. Hence, they are not capable of independent existence and always require a host. Due to absence of chromosomes, they do not undergo meiosis too.
