hmmm

Can you give me a sentence to write :D?

somy · Answer

yes, since mRNA is to be transported out for translation

anonymous · Answer

So my sentence is good?

somy · Answer

u can say that 
say it this way
mRNA translation is controlled by mRNA having a poly A tail

anonymous · Answer

Okay thank you @Somy !!!!!!

somy · Answer

meaning that poly A tail at the end of each mRNA controls how much of mRNA can be translated :)

anonymous · Answer

Yeah I figured that :D
