Investigation of neurons

I have been given the question below and have come up with an answer but I am really not sure of my answer. But this is the best I could do after looking through all the resources I had access to. Can someone please look at my answer and see if what I have written makes sense and if its right? Thank...

motor neuron early and late differentiation.

Hi everyone, Really need some help. I need to know how the later differentiation of different types of motor neuron takes place and an experiment that can be used to investigate the effects of different target muscles on the properties of the motor neurons that innervate them, a property of the neur...

MHC II molecule

I would be grateful if someone could help me here. Below is a molecular model of MHC II with an antigen bound to it. There are three residues which are covalently bound to the MHC class II molecule coloured in pink, but which do not form part of the polypeptide chains: two are attached to the A-chai...

Re: X Ray crystallography & transmembrane proteins

I have read up on x-ray crystallography but can't see why it would be different for the transmembrabe portion. I think it could be to do with the size or complexity but to be honest i didnt quite understand how cyrstallography works anyway.

I would appreciate any help anyone could offer.

Thanks

Molecular modelling

Describe the C-terminal domains of the A- and B-chains of the MHC class II molecule, with particular reference to their secondary structure. What type of module do these domains represent? What does it mean by 'module'? Can anyone explain what a 'module' of a protein is. The protein the question is ...

X Ray crystallography & transmembrane proteins

why is it difficult to obtain crystallographic data on the transmembrane portion of molecules? Can someone please explain this to me asap?

Thanks so much.
