<p>*Friedrich Miescher : identify the DNA and then RNA</p> <p>Q. I think DNA chip and RNA seq&nbsp;are the methods that measure&nbsp;the quantity of the RNA<br />is there any method which measures the quality of the RNA<br />I mean for example the half-life of RNA. (big database?)</p> <p>=&gt; the correlation btw protein level and RNA level in human is lower that in prokaryote. it is more complicate.</p> <p>*exercise : change in 30min (RNA which is related with signaling or TF will be a key, not genome), functional protein will be also a key.</p> <p>Conclusion : sudden environmental change =&gt; check RNA!</p> <p>How fast transcription</p>
