For bigger molecules, it is common for hybrid constructions to form – a loop on a toroid can prolong right into a plectoneme. If all the loops on a toroid lengthen, it becomes a department point in the plectonemic construction. DNA supercoiling is important for DNA packaging inside all cells. Because the size of DNA could be 1000’s of times that of a cell, packaging this genetic materials into the cell or nucleus (in eukaryotes ) is a tough feat. Supercoiling of DNA reduces the area and allows for far more DNA to be packaged. You possibly can strive both methods to learn which one works best for you.
