Question

Infinity Learn · Accepted Answer

Viruses are obligate parasites.They are inert outside their specific host cell.W.M. Stanley (1935) showed that viruses could be crystallised and crystals consist largely of proteins. No virus contains both RNA and DNA.The protein coat called capsid made of small subunits called capsomeres, protects the nucleic acid.
