Figure 11. Fluctuation of a m long chain with persistence length nm confined in a 60 nm 60 nm channel.

From bottom to top: (1) : no nicks; (2) : 10 nick in m; (3) : 50 nicks in m; (4) : 100 nicks in m; (5)□ : 200 nicks in m. This figure shows that when the density of nicks is lower than nicks per m, or nick per kbp of DNA, the fluctuation profile is almost the same as that for a chain without nicks.
