Viruses are between 20 and 100 times smaller than bacteria, or about 450 nanometers (. 000014), being the largest, to 30 nanometers (0.000001 in.) being the smallest which make them virtually impossible to be seen by light microscopes. Viruses often damage or even kill the cells they infect. They reproduce by releasing their nucleocapsid, or a copy o...
