Question

Quizplus · Accepted Answer

Epigenetic changes can involve modifications to the DNA or associated proteins that can affect the accessibility of specific regions of the genome to the transcription machinery. These changes do not involve alterations to the DNA sequence itself and can result in different patterns of gene expression in different cells or tissues, leading to distinct phenotypes. These changes can be temporary or stable, depending on the specific modification and the context in which it occurs.
