  that when delivered into cells again will activate this process of
  当这段序列被转入细胞后会激活
• 
  
  natural degradation of an existing messenger RNA.
  对已有信使RNA进行降解的过程
• 
  
  Of course,
  当然
• 
  
  if you degrade the messenger RNA at a rapid rate
  如果降解信使RNA的速度很快的话
• 
  
  then you'll stop expression of the cells.
  就会停止细胞的表达
• 
  
  Now the nice thing about this is that the degradation mechanisms seem to persist for some period of time,
  而好消息是降解过程会持续一段时间
• 
  
  beyond the time at which you deliver the double stranded RNA; whereas,
  比你转入双链RNA的时间要长 但是
• 
  
  obviously,
  显然
• 
  
  this mechanism here is only going to exist for
  这种机制只会在
• 
  
  as long as the anti-sense sequence is present.
  有反义链的时候发挥作用
• 
  
  So this might be a longer lasting,
  所以这似乎是一种持续时间更长
• 
  
  more permanent form of elimination of expression of a particular gene.
  更长久地阻止某个特定基因表达的方法
