男人和女人有许多明显不同的地方,以往认为所有这些不同背后的本质原因隐藏在我们的第23对染色体——X和Y染色体中,过去的绝大部分研究都集中在这两个基因是怎样编码蛋白质从而决定性别的。最近,美国冷泉港实验室(CSHL)科学家发现,还有一种非常小的亚基因单位能编码一种短RNA分子(mi RNAs),在区别两种性别方面也发挥着关键作用。相关论文发表在最近的《遗传学》杂志上。
There are many distinct differences between men and women, and the underlying causes behind all these differences in the past are hidden in our chromosome 23 - X and Y chromosomes. Most of the past research has focused on how these two genes are Encoding proteins thus determines sex. Recently, scientists at the Cold Spring Harbor Laboratory (CSHL) in the United States found that there is another very small subunit that encodes a short RNA molecule (miRNAs) that also plays a key role in distinguishing two sexes.
