A clock constructed of rDNA methylation sites can estimate both chronological and biological age across species.

Clinical analyses of patients’ gene sequences are helping to provide answers where none were available before.

New technologies reveal the dynamic changes in mouse and human embryos during the first week after fertilization.

The switch from maternal factors involves dynamic reprogramming of the zygotic genome.

Researchers are just beginning to scratch the surface of how several newly recognized epigenetic changes function in the genome.

To expand the basic nucleotide alphabet, many species modify their DNA with epigenetic marks.

Unlike animals, plants stably pass on their DNA methylomes from one generation to the next. The resulting gene silencing likely hides an abundance of phenotypic variation.

Multiple molecular mechanisms keep plant DNA methylation in order.

Researchers attempt to estimate how much of the human genome’s methylation patterns can be attributed to genetic ancestry.
