Virology Lectures 2024 #6: Synthesis of RNA from RNA

Host cells have no enzyme that can replicate viral RNA or make mRNA, so virus genomes must encode enzymes to carry out these processes. In this lecture we discuss the mechanisms of RNA synthesis by RNA dependent RNA polymerases, including priming of RNA synthesis, how mRNA and genomes are produced in infected cells, and the switch from synthesis of mRNAs to genomes, for negative strand RNA viruses, positive strand RNA viruses, and double-stranded RNA viruses.

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, podcasts, and more. New videos are uploaded several times each week. I do not run ads on our work as it is disruptive to learning.
