What is the smallest genome that can sustain an infectious agent? Might the genome of an infectious agent encode no protein? Could an infectious agent exist without a genome? Answers are provided by the remarkable viroids - small RNAs that encode no proteins - satellite viruses, and prions - infectious proteins that cause diseases like Creutzfeldt-Jakob and bovine spongiform encephalopathy, or mad cow disease.

– Who Am I? –
I’m Vincent Racaniello, Earth’s Virology Professor, and I believe that education should be free.
I’m also a professor of virology at Columbia University in New York. I’ve been doing research on viruses since 1976, and teaching virology in classrooms and online since 1999. On this YouTube channel I share videos of my lectures, MicrobeTV podcasts, and more.
New videos are uploaded several times each week.
I do not run ads on our work as they are disruptive to learning. We depend on your support.
