查询词典 quadruplex

It is well reported that human telomeric DNA sequence [AGGG3] can form a well-defined quadruplex structure with the hydrogen bond between guanine bases in the appearance of K+ and Na+. It was reported that the formation and stability of the structure is meaningful for both gene regulation and apoptosis.

据文献报道，人类染色体端粒中的重复序列[AGGG3]可以在钠、钾离子存在的条件下通过四个G碱基间形成平面环状氢键从而折叠成四链结构G-quadruplex，此结构的形成与稳定对基因调控以及细胞的凋亡有着重要意义。
