  and these are the biological mechanisms that are involved here
  幻灯片上给出了这些涉及的生物机理过程
• 
  
  and only shown by orange arrows on this slide.
  并将它用橙色的箭头指示出来
• 
  
  The end result is
  最终的结果是
• 
  
  you can design now very specific
  你现在能够设计针对性很强的
• 
  
  double stranded RNA sequences,
  双链RNA序列
• 
  
  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
