Virology Lectures 2024 #7: Transcription and RNA processing

Описание: Transcription is the synthesis of mRNAs from a double-stranded DNA template. Not all DNA viral genomes are ready for transcription, so upon entry into the cell they must converted into dsDNA. In this lecture, we discuss DNA dependent RNA polymerase, regulation of transcription by viral proteins, positive feedback loops and transcriptional cascades, RNA processing, the addition of 5'-cap, poly(A) tail, splicing, and RNA export, methylation of mRNA and the numerous small RNAs in cells and their functions.

– 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, 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. We depend on your support.
