近期,科学家通过对果蝇的研究发现了控制睡眠时间长短的基因,这有望解决人们对睡眠时间长短的不同需求。研究表明,果蝇睡眠大幅度减少是由于体内X染色体上一种“摇摆基因”发生了突变。睡眠少的果蝇在刚刚睡醒时腿会不停地颤抖。科学家发现那些睡眠少的人也有这个特点,这说明人 Recently, scientists found that the control of fruit flies, the length of sleep control of genes, which is expected to solve people’s different needs of the length of sleep. Studies have shown that a substantial decrease in Drosophila sleep is due to a mutation in a “swinging gene” on the X chromosome in the body. Drosophila less sleep in the wake of the leg will keep shaking. Scientists have found that those who sleep less have this feature, which shows that people
