Discussion of all aspects of cellular structure, physiology and communication.
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 it creates RNA and proteins?
An RBC is pretty much just a bag of hemoglobin anyway - not a lot of metabolic processes there.
Not sure about the oocyte, but I know enough to know NOT to apply "rules" of what can and can't happen at certain times to real-world biological systems. Biology is a system of exceptions.
RBC make everything they need before fully functioning, and then get rid of their nucleus.
About primary oocyte, are you perhaps thinking that since the chromosomes are so tightly wound, that they cant be used to produce proteins? There are regulatory proteins that allow transcription to happen. Am I knocking up the right tree here?
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 primary oocyte stops at the middle of it (diplotene stage) proteine production shoud be stopped as well.. so the same problem as in RBC - how it can survive for years withouth protein production
Erythrocytes do not survive for years. I actually think the average life expectance is 3 weeks?

yes 120 days.
