Or loops in DNA/RNA

according to my diagram: if the polymer is an isolated chain in smaller
molecules,
the longer, the more like Stokes, which is basically Zimm.

this chain is very very very....... long, long enough to reach a macroscopic
size to get ride of the surface effect.

| c*******n 发帖数: 1648 | 6 I totally agree, and I am very very veli.. interested in your first sentence.
Could you explain a little bit more?

| c*******n 发帖数: 1648 | 7 Hehe, this is also one of my questions, if the knot has something to do with
the entanglement, why stiffer chains are generally easier to be entangled
than flexible chains. I guess flexible chains are easier to form kont(my
guess?)
