Single nucleotide polymorphisms (SNPs) are the most common types of genetic variation among people.
In one of the largest epigenome-wide association studies, scientists have identified an epigenetic mechanism that alter the risk of obesity-related disease.
Insights from epigenomic maps will help determine the role the epigenome plays in learning, memory formation, brain structure and mental illness.
In normal development, all cells turn off genes they don't need, often by attaching a chemical methyl group to the DNA -- a process called methylation
The choreography of human brain development is amazing, but quite mysterious.
Deoxyribonucleic acid (DNA) is the chemical compound that contains the instructions needed to develop and direct the activities of nearly all living organisms. DNA molecules are made of two twisting, paired strands, often referred to as a double helix.
Scientists have uncovered intriguing new evidence helping to explain one of the ways in which a stem cell's fate can be determined.
DNA basics: What it is, what it does, and where it's found
