【动态】英法科学家最近发现了生命体内24小时生物钟的控制机制。英国剑桥大学的科学家首次发现血液里的红细胞有24小时生物周期节律。这一发现意义重大,生物钟控制着生物体的日常行为模式和季节性活动方式,生物周期节律一向被认为与DNA和基因活动有关,而成熟的红细胞没有细胞核和线粒体,没有DNA。他们的研究发现一种存在于所 [Dynamic] British and French scientists recently discovered the control mechanism of the body’s 24-hour circadian clock. For the first time, scientists at the University of Cambridge in the United Kingdom found that there is a 24-hour circadian rhythm of red blood cells in the blood. The discovery is of great significance. The circadian clock controls the daily patterns of behavior and seasonal activity of organisms. Biological circadian rhythms have always been associated with DNA and gene activity. Mature red blood cells have no nucleus and mitochondria, no DNA. Their study found that one exists
