we had the structure mentioned on bio class.. i don't know whether i've got the right spelling- quantosome, kvantosome.. but i would be really surprised if it didn't exist:)

yes.. i ment antigens:) and i know that they cause the immunological response when blood of different type is donated, but that is their primary function? do the antigens cause response in the presence of some other substances than donor blood:) ?

ok.. and i have another question concerning RBC. What is the function of the antibodies expressed on their surface (ABO system) and are there any functional differences btw. the antibodies of different blood groups?

sorry i wasn't here at the weekend:).. well, i agree with those RBC (i have the same explanation, i was just doubtful whether RBC can survive just with the proteins made before the maturation) what i meant in the case of the oocyte was, that during division the transcribtion is halted and since the ...

and the proteins they have made before maturation is sufficient to supply their function? aren't there different sources of proteins or other ways of their production?
and what about that primary oocyte?

RBC

Are mature RBC capable of protein production when they do not have nucleus? How are they able to transcribe RNA for protein production (they need new proteins.. to repair etc. right?). And similarly when primary oocyte stops its division at diplotene stage is it capable of transcribtion? if not, how...

Dyneins& Kinesins

i was wondering, what happends to a dynein (or a kinesin), when it reaches the end of the microtubule (when it has transported the cargo and its role is over). It is just destroyed or the microtubules are conected in a way that dynein can continue and carry something else somewhere?
