DNA supercoiling parameters IA "relaxed," circular, double-stranded DNA molecule (...

DNA supercoiling parameters I

A "relaxed," circular, double-stranded DNA molecule (1600 bp) is in a solution where conditions favor 10 bp per turn. What is the value of Lo for this DNA molecule? Suppose DNA gyrase introduces 12 negative supercoils into this molecule. What are the values of L, W, and T now? What is the superhelical density,σ?
