We have previously discussed the idea that viruses originated from selfish genetic elements such as plasmids and transposons when these nucleic acids acquired structural proteins (see A plasmid on the road to becoming a virus). I want to explore in more detail the idea that the structural proteins of viruses likely originated from cell proteins (link to …
Jonathan Yewdell, Chief of the Cellular Biology Section at the National Institute of Allergy and Infectious Diseases, has written a book entitled Truth Wins: A Practical Guide to Succeeding in Biomedical Research. Dr. Yewdell is well known for his presentations about the problems with biomedical science, a subject we discussed on TWiV 208: The Biomedical …

Chemical modification of RNA by the addition of methyl groups is known to alter gene expression without changing the nucleotide sequence. The addition of a methyl group to adenosine has been found to regulate gene expression of animal viruses, and most recently of plant viruses. The illustration shows a methyl (CH3-) group added to the …
Vincent speaks with 1993 Nobel Laureate Phillip A. Sharp about his career and his seminal discovery of RNA splicing in mammalian cells, which changed our understanding of gene structure.
