Study Notes
Epigenetics Study Notes
Definition and Scope
- Epigenetics is the field of study that explores how behaviors and environment can cause changes in gene function.
Cellular Components
- Chromatin is responsible for packaging DNA into more compact structures in eukaryotic cells.
- Histones are proteins that DNA wraps around to form chromatin.
Epigenetic Modifications
- A record of chemical changes to DNA and RNA is known as epigenetic modifications.
- DNA methylation involves the addition of a methyl group to DNA.
Characteristics and Inheritance
- Epigenetics is characterized by changes in gene function that do not involve a change in the DNA sequence.
- Environmental factors have been shown to affect not only the original organism but also their offspring and grandchildren.
- Epigenetic effects can be passed on to future generations.
Key Concepts
- Epigenetic effects can be influenced by environmental factors, such as behaviors and lifestyle choices.
- Chromatin remodeling plays a crucial role in gene expression and epigenetic regulation.
