The discovery of viruses resulted from the search for the infectious agent causing tobacco mosaic disease. In 1935, Wendell Stanley isolated tobacco mosaic virus, making it possible to carry out chemical and structural studies on a purified virus. Viroids are infectious pieces of RNA that cause some place diases

Process and Techniques of Finding Unknown J Abstract: As part of a focal study within Microbiology, many scientists have endeavored to identify the many species and types of microbes found in different environments. In an effort to categorize, understand and distinguish one microbe from another, scientists developed tests to show unique characteristics of microbes. This experiment enlists these tests, such as PCR, Simple and Gram staining, anaerobic growth tests, IMViC, Catalase, Oxidase, selective
