DNA Coiling and Topoisomerase
how to sketch the writhe accurately with a topoisomerase I to alter the structure.
Please draw a circular DNA molecule that contains 3 negative supercoils. In this DNA molecule, make L = 250 and T = 253. Don't draw the details here i.e., all 250 of the strand passages around each other. Focus on sketching the writhe accurately. Now imagine adding a type I topoisomerase. Draw the three most likely products, write the values for L, T and W for each molecule.
