越来越多证据表明DNA并不是亲代将遗传信息传递到子代的唯一方式。亲代在一生当中经历的许多事件都会对遗传信息的传递产生影响。最近,来自宾夕法尼亚大学的研究人员在国际学术期刊PNAS上发表了一项最新研究进展,他们在分子水平上发现了应激如何改变雄性小鼠的精子,并通过这种方式影响其后代对应激的应答情况。他们还发现这种变化是通过表观遗传学的方式或microRNA进行传递的,并非通过改
There is growing evidence that DNA is not the only way parents can pass on genetic information to their offspring. Many events that parents experience throughout their lives have an impact on the transmission of genetic information. Recently, researchers from the University of Pennsylvania published a new study on the PNAS, an international academic journal that found at the molecular level how stress changes sperm in male mice and in this way affects the offspring’s response to stress Answer situation. They also found that such changes were passed through epigenetics or microRNAs, not through change
