Epigenetics Definition

Epigenetics is the study of heritable changes in the control of gene expression. This is done by not modifying the DNA code (no change to nucleotide sequence) itself but modifying the way DNA is controlled and packaged in the cell. Epigenetics stands for epi- (Greek meaning above, over) and -genetics. Epigenetic changes can include DNA methylation and histone modifications. These both act to regulate gene expression and they are inherited through cellular division for the cells entire life in addition to future generations.

Epigenetics plays a role in genomic imprinting, cancer development, transgenerational epigenetics, developmental abnormalities, twins and in cancer treatments.

Epigenetics vs Genetics

Epigenetics is the study of gene expression and changes that do not change the DNA code or the DNA sequence. Basically the study of changes on DNA that do not effect the code itself. For example, changing the cover of a book from black to white. You do not change any of the text, just the way it looks. Genetics is the study of the DNA code/DNA sequence itself and the changes of the code. For example, this is like editing a book and changing the words within the text.
