ATCA synchronizes translation?

My understanding of ATCA is that it covalently links to the RNA.  When this
occurs, the RNA is no longer competent for either in vitro translation or
transcription.  Thus you would synchronize translation by elimating the
mRNA pool (and any additional translation) after the initial 3 minutes of
the experiment.  I do not know how quickly the ATCA actually inactivates
the RNA.
