Abstract:

为研究染色质重塑因子对核小体定位的影响以及ISW2缺失情况下基因功能对核小体形成的作用，本文分别对ISW2敲除、野生型(WT)及富营养培养条件下(YPD)三种酵母核小体占位率数据进行聚类、比较、分析后发现，在ISW2缺失情况下核小体的位置远离TSS，同时发现11种基因功能对核小体的定位产生了显著影响。
To study the impact of chromatin remodeling factor on nucleosome positioning and the function of gene in the formation of nucleosomes in the absence of ISW2, this paper compares and analyzes the data on the proportion of nucleosomes in three kinds of yeasts, which are cultured without ISW2, WT or in YPD. The study finds that in the absence of ISW2 the nuclesomes are far from TSS and that 11 genes impose noticeable impact on nuclesome positioning.
