Brownian dynamics simulation of the cross-talking effect among modified histones on conformations of nucleosomes
《Chinese Physics B》2010年第4期461-468,共8页段兆文 李伟 谢平 窦硕星 王鹏业 
Project supported by the National Natural Science Foundation of China (Grants Nos. 10834014 and 10674173);the National Basic Research Program of China (Grant No. 2009CB930704)
Using Brownian dynamics simulation, we studied the effect of histone modifications On conformations of an array of nucleosomes in a segment of chromatin. The simulation demonstrated that the segment of chromatin shows...

Modelling of a DNA packaging motor
《Chinese Physics B》2009年第11期4852-4864,共13页钱钧 谢平 薛晓光 王鹏业 
Project supported by the National Natural Science Foundation of China (Grant Nos 10834014 and 10674173);the National Basic Research Program of China (Grant No 2009CB930704)
During the assembly of many viruses, a powerful molecular motor packages the genome into a preassembled capsid. The Bacillus subtilis phage φ29 is an excellent model system to investigate the DNA packaging mechanism ...

Spermidine-induced two-dimensional DNA condensations on mica surfaces:A different pathway from condensations in solution
《Chinese Science Bulletin》2009年第14期2425-2433,共9页ZHANG XingHua HOU XiMiao JI Chao LIMing DOU ShuoXing WANG PengYe 
Supported by the National Natural Science Foundation of China (Grant Nos. 10834014, 10674173);National Basic Research Program of China (Grant No. 2009CB930704)
With atomic force microscopy (AFM) we systematically studied the DNA condensations on mica surfaces induced by multivalent cation spermidine. The pattern of the DNA condensates is a flat single layer, with a core in t...

Spherical/gyroid phase diagram of the diblock copolymer in the median selective solvent
《Science China(Physics,Mechanics & Astronomy)》2009年第4期518-523,共6页ZHANG LingYun WANG PengYe SHI An-Chang 
Supported by the National Natural Science Foundation of China (Grant Nos. 10834014, 10674173, and 30770517);the National Basic Research Program of China (Grant No. 2009CB930704)
The effect of the median selective solution on the lamellar,spherical and gyroid structures is studied. The self-consistent field equations of the diblock copolymer solution are solved by using the reciprocal space me...

Monte Carlo simulation on backward steps of single kinesin molecule
《Chinese Physics B》2008年第4期1513-1517,共5页王宏 张勇 窦硕星 王鹏业 
Project supported by the National Natural Science Foundation of China (Grant Nos 10334100 and 10674173)
Kinesin is a stepping molecular motor travelling along the microtubule. It moves primarily in the plus end direction of the microtubule and occasionally in the minus-end, backward, direction. Recently, the backward st...
