In their natural habitats, organisms encounter numerous external stimuli and must be able to sense and adapt to those stimuli to survive. Unlike mutations, epigenetic changes do not alter the underlying DNA sequence. Instead, they create modifications that promote or silence gene expression.

细菌表观遗传学及其对农业、益生菌开发和生物技术设计的影响


在自然栖息地中，生物体会遇到许多外部刺激，并且必须能够感知并适应这些刺激才能生存。与突变不同，表观遗传变化不会改变潜在的 DNA 序列。相反，它们会产生促进或沉默基因表达的修饰。
