That's a really good question because if I open this up, why wouldn't it just reform with itself, why would it want to have this in here?

The answer is it will want to reform with itself, and if I have these in solution then how many reform with itself and how many reform with the molecule I'm interested probably depends on the relative concentrations of both in the solution and what conditions I have it at.

答案是质粒有可能会自己闭合,如果质粒和我感兴趣的DNA片段,都在溶液里那有多少质粒会自己合上,有多少与我感兴趣的DNA重组呢,这大概取决于两者在溶液里的相对浓度,和我让溶液处在什么条件下
