I was thinking of editing this stub to use simpler language and explain exactly what a daisy chain of DNA is. The change I want to make is for the article to say this: "Daisy chaining DNA is the process of when DNA undergoing PCR becomes tangled and forms a 'daisy chain.' During PCR, primers or dNTP's will eventually be used up and limit further reactions; it is when the primers deplete that causes daisy chaining. Since the denaturing and annealing processes still continue without primers, the single-stranded DNA molecules reanneal to themselves. However, this reannealing does not always occur to another complementary strand. It is this imperfect match up that causes 'tangles'. These tangles look like a daisy chain."  
 I used this source, and will of course site it.  
 Thoughts? (  )
