Learn Genetics – Epigenetics

What is Epigenetics?

As an organism grows and develops, carefully orchestrated chemical reactions activate and deactivate parts of the genome at strategic times and in specific locations. Epigenetics is the study of these chemical reactions and the factors that influence them.

The Epigenome at a Glance

Meet the epigenome and learn how it influences DNA.

Gene Control

Change the level of gene expression in a cell with the turn of a dial!

The Epigenome Learns From Its Experiences

Epigenetic tags record the gene-regulating signals the cell receives.

Epigenetics & Inheritance

Parents have a role in shaping the epigenomes of their offspring.

Genomic Imprinting

Certain genes are silenced during egg and sperm formation.

The epigenome dynamically responds to the environment. Stress, diet, behavior, toxins, and other factors regulate gene expression.

Insights From Identical Twins

Why do identical twins become more different as they age? See how the environment affects the epigenome in a pair of twins over time.

Lick Your Rats

What kind of mother are you? Care for a rat pup and shape its epigenome.

Nutrition & The Epigenome

What you eat can change your gene expression.

Epigenetics & The Human Brain

Epigenetic mechanisms play an important role both in normal brain function and in mental illness.
