Hi, netters,

I have a question to ask. Does every mRNA have a AATAAA signal to stop 
transcription. IS the AATAAA sequence necessary for any mRNAs? I did 3'RACE
and at upstream 20 bp of polyA, I found the AAAAATAA sequence. Does this 
sequence stop transcription. IN other word, How can I know that I get the 3' 
end of transcripts. 

Thank you in advance.
