Expert Answer
Ans. Viruses are infectious agents of small size and simple composition that can multiply only in the living cells of animals, plants, or bacteria. The genetic information encoded in nucleic acids of viruses enables them to reproduce, synthesize unique proteins and alter cellular functions to be studied. Due to their ability of self-replication and purity, viruses can be easily made into crystals. In 1935, tobacco mosaic virus (TMV) became the first virus to be crystallized. In 1955, the poliomyelitis virus was crystallized.
