It is ascertained that the PABA may be N-dimethylated using dimethyl sulfate as a methylation agent.

确定以硫酸二甲酯为N——甲基化剂,对对氨基苯甲酸PABA进行N——二甲基化.

Both MSAP (methylation sensitive amplification polymorphism) ratio and full methylation level were the highest in bracteal leaf, and the lowest in tassel.

同一织在两个自交中的甲基化水平也存在差异。

In the fields of epigenetics and epigenomics, DNA methylation has been drawn a special attention because of its close correlation to human development and carcinogenesis.

DNA甲基化已经成为表观遗传学和表观基因学的重要研究内容，人类表观基因计划的最终绘制出人类基因中甲基化可变位点图谱。
