Question

TMV contains a genetic material
(a) DNA
(b) RNA
(c) DNA and RNA
(d) Chromosome

Answer 1

Most viruses either contain RNA or DNA as their genetic materials. The plant viruses have RNA as their hereditary material. However, the nucleic acid found can be both single or double stranded.

The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein.

The simplest viruses contain only enough RNA or DNA to encode four proteins. The most complex can encode 100 – 200 proteins.
