Can histone modifications be heritable

WebAug 8, 2024 · Epigenetics is the study of heritable and stable changes in gene expression that occur through alterations in the chromosome rather than in the DNA sequence. Despite not directly altering the DNA sequence, epigenetic mechanisms can regulate gene expression through chemical modifications of DNA bases … WebIn general, epigenetics refers to heritable changes in gene expression that are, unlike mutations, not attributable to alterations in the sequence of the DNA . Among the epigenetic events are: DNA and histone modifications, ATP-dependent chromatin remodeling complexes and non-coding RNAs [5,6,7,8]. In this review, we first provide a description ...
