Feb 25, 2015 · Therefore those organisms require a more stable form of their DNA which can be achieve by positive-supercoiling and/or high GC content. Now why do the vast majority of the …

2 The DNA exists in linear and cirular forms. The latter form has interesting feature called Supercoiling. The more number of writhe makes it more supercoiled because of which it gets more compact. …

While trying to understand DNA supercoiling, I came across these lines in the book Genetics by Ursula Goodenough : All natural DNA is superhelical. The axis of the duplex itself follows a helical

When a twist is unwound without cutting the DNA strands or is removed by cutting the strand(s) and resealing, negative supercoils are introduced in the DNA. From Cell and Molecular Biology -Karp But
