It describes the differences between bacteria and viruses, and between DNA and RNA viruses. It covers virus structure, classification, life cycles, methods of transmission between hosts, discovery, theories of origin, and techniques for studying and cultivating viruses. Understand how viruses infect cells and the difference between lytic and lysogenic infections. In 1935, biologist Wendell Stanley of the Rockefeller Institute purified tobacco mosaic virus (TMV) and determined that the purified virus is a crystal, which only chemicals do. Early discoveries included Lady Montagu observing inoculation against smallpox in Turkey in the 18th century and Edward Jenner developing the smallpox vaccine using cowpox virus in 1798. In 1892, Dmitry Ivanovsky used filters to show that extracts from infected tobacco plants remained infectious after filtering out bacteria.
