The first of these organisms to be discovered was proposed to have a hollow, helical structure by Rosalind Franklin, and is known as the "tobacco mosaic" kind.
These organisms can be grouped into seven categories in a classification system developed by David Baltimore. Some of these organisms contain an env gene that codes for lipids and glycoproteins to form their namesake envelope. The first of these organisms to be discovered was proposed to have a hollow, helical structure by Rosalind Franklin, and is known as the "tobacco mosaic" kind. The T4 bacteriophage is an example of a double-stranded DNA version of these organisms. Some of these organisms use reverse transcriptase to integrate DNA into the host cell. For 10 points, name these pathogens made of DNA or RNA surrounded by a protein coat, such as HIV.
