From the following set of statements regarding DNA topology, state whether each of the given statement is either True or False.
A. The two strands of cccDNA can be easily separated without any breakage of bonds.
B. Circular DNA molecules purified from bacteria and eukaryotes are usually negatively supercoiled.
C. Interwound writhe and spiral writhe are topologically different.
D. The organisms that live under extreme temperature conditions have been found to have positively supercoiled DNA.
E. Negative supercoils can be thought of as a store of free energy that aids in processes that require strand separation.
