Homework Help: Biochemistry

Posted by Anonymous on Thursday, October 31, 2013 at 1:07am.

a closed circular DNA molecule has 3675 base pairs and a topological linking number (Lk) of 345. Using 10.5 base pairs per turn, what would the writhe number (Wr)be for the molecule in order for it to optimize its base pairing??

I'm guessing we use the formula Lk= Tw+Wr.

However what is Tw?
