Geneticists study the gene; however, for epigeneticists, there is no obvious 'epigene'. Nevertheless, during the past year, more than 2,500 articles, numerous scientific meetings and a new journal were devoted to the subject of epigenetics. It encompasses some of the most exciting contemporary biology and is portrayed by the popular press as a revolutionary new science--an antidote to the idea that we are hard-wired by our genes. So what is epigenetics?
遗传学家研究基因;然而,对于表观遗传学家来说,却没有明显的“表观基因”。尽管如此,在过去一年里,有超过2500篇文章、众多科学会议以及一本新期刊都致力于表观遗传学这一主题。它涵盖了一些当代最令人兴奋的生物学领域,并且被大众媒体描绘成一门革命性的新科学——是对我们由基因决定这一观点的一种修正。那么,表观遗传学究竟是什么呢?
