Description |
Base pair opening in an inhomogenous double helical molecular chain with flexible strands is studied by solving the governing dynamical equations analytically and numerically. The results show that inhomogeneity in stacking and hydrogen bonds in localized and periodic forms and the helicity do not alter the amplitude of the bubble soliton. However the flexibility of the strands makes the amplitude to damp. On the otherhand the velocity of the bubble soliton is unaltered. Further the above effects introduce small fluctuation in the tail of the bubble soliton without affecting the robust nature of the soliton during propagation. |
