    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.
