周期驱动DNA的动力学相变

Dynamical phase transition of a periodically driven DNA

Garima Mishra, Poulomi Sadhukhan, Somendra M Bhattacharjee, Sanjay Kumar

摘要:

复制和转录是生命系统中的两个重要过程。为了执行这样的过程,各种蛋白质以交错的方式远离平衡地工作。受此启发,在非平衡条件下的周期性驱动下的DNA解压缩过程中的滞后方面进行了研究。提出了一个驱动DNA的稳态相图,这是实验验证。作为一个两态系统,我们还比较了DNA和Ising磁体在非对称变化的磁场下的结果。

英文摘要:

Replication and transcription are two important processes in living systems. To execute such processes, various proteins work far away from equilibrium in a staggered way. Motivated by this, aspects of hysteresis during unzipping of DNA under a periodic drive in non-equilibrium conditions are studied. A steady state phase diagram of a driven DNA is proposed which is experimentally verifiable. As a two state system, we also compare the results of DNA with that of an Ising magnet under an asymmetrical variation of magnetic field.
