Cell Biology 06: The Cytoskeleton Part II: Tubulin. These are notes from lecture 6 of Harvard Extensionâs Cell Biology course. Last week we covered microfilaments, which are made of actin. This week: microtubules, made of tubulin. Why, you ask, does the cytoskeleton need two separate systems? Consider that microfilaments are just chains of individual subunits, whereas microtubules are literally tubes (as weâll see shortly) â hollow cylinders with walls made of chains made of dimers.
Animals (Nickelback song) Animals is a song recorded by Canadian rock band Nickelback. It was released in November 2005 as the second single from their fifth studio album, All the Right Reasons. The song was played at the 2011 Tribute to the Troops.
Jetsons: The Movie was originally slated for a 1989 release, but was delayed to avoid competition with Disney's The Little Mermaid, United Artists' All Dogs Go to Heaven (which were both released on the same day), Universal's own Back to the Future Part II and Warner Bros.' National Lampoon's Christmas Vacation.
