  We're going to have DNA that we would like to make lots of copies of,
  我们将那些需要得到很多拷贝数的DNA
• 
  
  or we're going to have DNA that we would like to get expressed in a cell,
  或者需要在细胞中表达的DNA
• 
  
  and we're going to put it in this region that's called the polylinker.
  整合到这个叫做多克隆位点的区域中
• 
  
  How we do that will be clear in a few minutes,
  马上你们就清楚这该怎么做了
• 
  
  but this polylinker as is described down here
  这里所说的多克隆位点
• 
  
  is a site where you can clone in genes.
  就是你能把基因片段插进来的位点
• 
  
  Let's assume that we have this plasmid cloning vector and
  假设我们已经有了克隆质粒载体
• 
  
  we have some pieces of DNA
  也有了我们想要将之
• 
  
  that we would like to put into a plasmid
  整合到质粒上的某些DNA片段
• 
  
  that we would like to make copies of.
  同时也是我们所要复制的DNA片段
• 
  
  DNA cloning,
  DNA克隆
• 
  
  or any kind of cloning just means 'making copies of'.
  或者任何一种克隆 本义就是"复制"
