I know this is a biology question but this is the most busy forum so I decided to put it here:
I'll make this simple. A restriction enzyme reads a DNA strand containing nucleotide base pairs. It cuts the strand after it reads a sequence of 6 base pairs - AAGCCT. Of course the probablity of the enzyme reading the correct base is 1/4. And it needs 6 of them.
So what is the average length of a cut strand? I'm thinking you do (1/4)^6 and this will give you something.. but what?
Thanks for your help in advance...
