What Is Epigenetics? - Cleveland Clinic
Epigenetics is a relatively new field of study that looks at how certain chemicals inside your body’s cells control how your genes work. Scientists call these chemicals epigenetic marks or chemical signatures.

2025年1月6日 · epigenetics, the study of the chemical modification of specific genes or gene-associated proteins of an organism. Epigenetic modifications can define how the information in genes is expressed and used by cells.
What is epigenetics? - MedlinePlus
2021年6月11日 · Epigenetic changes are genetic modifications that impact gene activity without changing the DNA sequence. Learn more about the process.
Epigenetics - Wikipedia
In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of ...
What is Epigenetics? The Answer to the Nature vs. Nurture Debate
2019年2月19日 · During development, the DNA that makes up our genes accumulates chemical marks that determine how much or little of the genes is expressed. This collection of chemical marks is known as the “epigenome.” The different experiences children have rearrange those chemical marks.

2019年9月1日 · What is epigenetics? Epigenetics is the study of biological mechanisms that will turn genes on and off. We simplify epigenetics with analogy examples.
Epigenetics: Fundamentals, History, and Examples | What is Epigenetics?
Epigenetics is the study of heritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes.
Epigenetics - National Human Genome Research Institute
1 天前 · Epigenetics is an emerging field of science that studies heritable changes caused by the activation and deactivation of genes without any change in the underlying DNA sequence of the organism.
