17nt melted, vound via the supercoiling the melting produced.
But, the static nature of the diagram is misleading. dsDNA is opening up
a. RNA is twisted around DNA strand
b. Lots of energy
c. No know enzyme
Rotation causes strain: Supercoiling relaxed by gyrase and topoisomerase.
+ supercoils ahead. – supercoils behind.
RNAP does not move.
1. initiation of replication AND
2. distribution of the duplicated template to daughter cells.
