英文摘要The conformations of DNA chains are studied under the elastic rod model by Metropolis Monte Carlo simulation. The energy of DNA chains includes the bending energy E-B, and the twisting energy E-T, and they can be expressed in the form of E-B(r) = A/2 integral(0)(L) kappa(2)ds and E-T (r) = 2pi(2) C/L (DeltaLk - Wr)(2). The energy decreases with increasing the chain length of DNA. We find that E,, is greater than E, by 10 _ 102 times. In the same time, the relationship between and chain length n is = 1169.5 - 3.5 x n + 0.025 x n(2). The equation of Lk = Wr + Tw is verified, and the values of Lk and Wr are found to be very close to each other. It shows that DNA chain is easier to be bent than to be twisted. But for the large value of Lk, the tendency of torsion becomes large. Our simulation can provide a new method to analyze the conformations of DNA chains.
