Street Corner Science Video

http://www.sciencentral.com/video In "Street Corner Science," a ScienCentral original Web Show, pedestrians are given the chance to sit down with a world-class scientist and him or her any question they like about science, or anything else on their minds. In this episode, renowned chemist: Dr. Stephen Benkovik answers a varied and astute array of questions from some lucky passersby.

i thought this was very good, even though i don't particularly enjoy biology, though it was very informative and it shows that everyone is effected by science. its just about time more people woke up to it

[farvision]

just give a link. I don't give my email out here.

This is how Satan's emissaries do evangelism.

The identical parts do. The missing parts don't (obviously). There are parts that don't participate (nearly 95% in humans), right enough, but errors happen. Androgen Insensitivity can be caused by this. You get an XY female. And the opposite, an XX male (the SRY gene gets swapped onto an X chromosome). The Y chromosome can use a sort of self-autosomal crossover with palindromic versions of the genes (same, but backwards).

Not a chance.  If they were preselected, he would have actually had good answers.

Wow, I'm surprised he gave a terrible answer to the first question. I think the guy left not only not very much enlightened but quite confused.

Anyway, congrats to Dr. Benkovik on his award and his outstanding career.

I was under the impression that the Y chromosome did not take part in homologous chromosome crossing over. You get that from you dad, intact.

[RyuDarragh]

Your genes are from your mom and dad. Half hers, half his. They play a game called "gene shuffling", too. And gene duplication and gene deletion. A males Y chromosome got that way due to gene deletion. Some diseases happen when the Y chromosome is stuffed with DNA from the X chromosome.

[ananiasacts]

I'd have asked him at what point in time my gene's came into existence. Then he'd have had to explain that the half I got from my mother were actually created while she was a developing fetus, but that the ones I got from my father were just a few weeks older than the point in time when I was conceived. That a man's genes are slightly older on average than a woman's because the Y chromosome is inherited intact, and that the mitochondrial DNA comes only maternally and is the oldest of all, etc.

You're just another cyberbitch afraid to show your face, I laugh at you for days.

[biggerflexible]

What the hell does that sentence fragment mean?

[itsabomberscope]

Pre-selected questions im sure.
