4. Molecular Genetics I

(April 5, 2010) Robert Sapolsky makes interdisciplinary connections between behavioral biology and molecular genetic influences. He relates protein synthesis and point mutations to microevolutionary change, and discusses conflicting theories of gradualism and punctuated equilibrium and the influence of epigenetics on development theories.

Funny that the majority of the specialised videos only have likes. Tends to shake off the haters :P

[masteranza]

This could be used as a definition of quality speech.

@JDexia

Yup. You won't find many trolls around such specialized videos.

@subetai17 I'm not really informed on that subject so i'll assume everything you said is true.

But not everyone in his classes have the back ground to understand all the concept which he talks about. If he was to properly explain each aspect in the main lecture he wouldn't have time to properly deliver the more important aspects of the class. Don't forget that they are also catch up session for poeple with out the back ground on a subject.

I'm sorry for my poor written english.

But there is still a limit to your epigenetics based on your genetics. IT can't be regulated in any way to transcribe anything whatsoever. No amount of regulation from epigenetics will turn a chimpanzee into a functional human.

Correction starting at 35:31. Don't say "some benzodiazepines are synthetic" - ALL are synthetic, starting with chlordiazepoxide, the first one synthesized at Hoffman La Roche. Second, benzodiazepines are NOT proteins - as the name suggests, they are simple heterocyclic molecules formed by the fusion of a benzine ring with a diazepine ring. Third, technically, there is no "benzodiazepine receptor". It's actually the GABA-A receptor receptor, with an allosteric binding site for benzodiazepines.

@sirLEVITSKY just for even mentioning her name i disliked your comment

[sirLEVITSKY]

This lecture is way better than Justin Bieber. Thumbs up if you're watching this in 2012!

@I3L4NK

You like to have sex, then!

Are u a female? :P

[FinixPoltergeist]

This was quite captivating.

[perchsmith]

Love it

Benzodiazepine is very harmful for the brain, it creates more problem in the neurotransmitters. I love this lecture, but the promotion of modern medicine is a very bad marketing idea.
