Virology Lectures 2023 #4: Structure of viruses

- Viral particles are a paradox: they must protect the genome in its journey among hosts, but also come apart under the right conditions to release the genome into cells, a property called metastability. This lecture explores the two major forms of symmetry for building virus particles, helical and icosahedral. We discuss quasi equivalence; how to make larger viruses by increasing the triangulation number; and the lipid envelope and its glycoproteins derived from the host cell.

- Who Am I? -
I’m Vincent Racaniello, Earth’s Virology Professor.
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 TH-cam channel I share videos of my lectures, podcasts, and more.
New videos are uploaded several times each week.

Uploading columbia lectures is such a godsend fr. I love learning virology thru these videos while i do my other actual bio course work at uni. You make it really interesting Vincent!
I have benefitted a lot from this class. My name is Gwengi - a student of pharmacy in Kenya
According to my text book, school notes, google AI bard , and Oxford dictionary the nucleocapsid refers to the capsid together with the nucleic acid it encloses. So that might be why so many are confused when you say your definition because nucleocapsid according to the other sources would be found in non enveloped and enveloped viruses
Thanks, watching from Kazakhstan
Excellent
Thanks for another lecture, it was great!
Thanks proff its very helpful...❤
Thanks Vincent! Amazing lecture!!
Looking at the illustrations of viruses early in this lecture, I am surprised by the similarity between the viral illustrations and photographs of diatoms.
thank you Vincent ,i enjoy the learning i get from your shows...
Ty for this
Thanks Vincent! Amazing lecture ....
Thank you professor 💚💚
I have a question. Does influenza virus have eight different nucleocapsids, one for each ot its -RNA segments? If so is that what defines its helical nature?😮 The virion image appears globular. I assume that is so because of the encompassing membrane? Thank you for answering this question. I did not catch this nuance in your previous versions of this lecture!
I think so, he grouped viral structure by capsid / nucleocapsid structure, , not by their structure itself. Even if the if Ebolavirus looked like round as influenza, it would stay as helical, not isohedrical.
"The bonding contacts of subunits are usually non-covalent." Are they not always non-covalent?
Don't get the term meta-stable in context of the protective role for viral genome
the mic bites on this one.....
