Certain nervous cells are several meters length in giraffes,whales... but in human some of the biggest neurons have cell bodies that are 100 micrometers wide and some skeletal muscle cells are several centemeters. :)

Sorry I didn't know that the link you were talking was on the forum. Do you think it is possible to find a link to download the book in intirety because chapiter by chapiter it will be very long.For working a paper version it much better,don't you think :)

I forgot to say that there is another possibility in an atmosphère composition wich was completely different. Maybe some other kind of molecules wich support life were be present and stable, and it is after that all the organic molecule that we know appeared.

My opinion is that the first wich appeared necessarily need to have at the same time an informative fonction and a catalic fonction, although RNA hasn't a high stability, it is for me the most serious candidate. If the subjet interest you I advice you to read, a conceptually marvellous book: The Sel...

I asked to a resheacher who works in biology of development and he explain me, actually the PKC takes not always the pathway of RAF, but it is unable to directly phosphorylate the MAPKs, it takes another pathway a little bit more complicated.
I thank to both for your help :wink:

Thanks Enzyme I've got the Stryer,5th edition that's the greatest book for biochemestry but this is not a good book for cellular biology, and it doesn't talk about MAPK,and if I am mistaken, gives me the chapter . Excuse me Sdekivit for my pitiful english but I would want to say that I never seen a ...

Action of Gq protein

Hi, I don't find references about the action of the Gq protein and my question is: The phospholipase C β(PLCβ) actives PIP2 and gives diacetylglycerol and IP3, this DAG actives the protein kinase C but I don't know if the PKC follow the phosphorylation way of RAS and RAF or if the PKC foll...

Scientist exportation

Hi everybody, It's the first time I submit and I don't know if it's the right place for it, but here's my question: I'm still learning in university and I'll soon graduate in molecular biology. I'm asking myself if I'm not going to leave my country, because in belgium there'isn't very much work for ...
