随着科学技术的不断进步,人类对自身奥秘的探索也在进一步加深。基因这一原本非常神秘的概念渐渐变得为人所知,对基因的研究也在逐步深入。通过在老鼠身上进行的实验,研究人员发现,暴露于环境毒素中,人类的基因会受到影响,从而导致一系列遗传性疾病的发生,如乳腺癌、高胆固醇等等这种毒素效果会影响到四代的雄性。华盛顿州立大学的分子生物学家迈克尔·斯金纳和他的同事们在一项新研究中发现化学残留物给老鼠后代带来的影响是一种非基因遗传。遗传学家称之为“表观遗传”,这种遗传并没有改变DNA顺序。众所周知,DNA顺序变化是基因突变的重要特征。这个研究结果为疾病的探索提供了一个新思路,有助于人们对遗传疾病产生过程的理解。
With the continuous advancement of science and technology, human exploration of its own mysteries is further deepened. The concept of genetics, which was originally very mysterious, gradually became known, and the study of genes was gradually deepened. Through experiments in rats, the researchers found that exposure to environmental toxins, human genes will be affected, resulting in a series of genetic diseases, such as breast cancer, high cholesterol, etc. This toxin effect will affect Four generations of males. Michael Skinner, a molecular biologist at Washington State University, and his colleagues found in a new study that the effect of chemical residues on the offspring of mice is a non-genetic inheritance. Geneticists call it “epigenetics,” and this inheritance does not change the DNA sequence. As we all know, DNA sequence changes are important features of gene mutations. This research result provides a new idea for disease exploration and helps people understand the process of genetic disease.
