epigenetic changes are heritable changes to the regulation of a cell’s genes, caused by extra molecules being attached to those genes.
表观遗传变异是由附属于基因的其他分子作用引起基因表达改变的可遗传的变异。
epigenetic mutations confer heritable changes in gene expression that are not due to changes in the underlying sequence of the dna.
表观遗传突变是指没有引起dna序列变化的可遗传的基因表达改变。
when biologists say that humans and chimps have evolved from a common ancestor they mean that there have been successive heritable changes in the two separated populations since they became isolate.
当生物学家说人和黑猩猩是由共同祖先进化来的时,他们的意思是,自从二者分野后,这两个隔离的种群都发生了延续性的可遗传变化。
epigenetics refers to heritable changes caused by mechanisms distinct from the primary dna sequence.
表观遗传学是指遗传变化的主要dna序列的机制不同所造成的。
epigenetics refers to the heritable changes in gene expression without any alteration in dna sequence, including dna methylation, histone modification and chromatin conformation.
表观遗传学是指基于非基因序列改变所致基因表达水平的变化,如dna甲基化和组蛋白修饰等;
epigenetics is defined as the investigation of heritable changes in gene expression that occur without a change in dna sequence.
表观遗传学是研究dna序列没有发生改变的情况下基因表达的遗传变化。
