Inheriting DNA cells can be weirder than you think. Chemical switches attached to DNA turn genes on and off or up and down, telling the machinery which proteins to produce and in what quantities. These swithces, called epigenetic tags, make for some very strange DNA passed down from our ancestors. Emily Elert explains in this fascinating edition of Minute Earth.

Ever since a monk called Mendel started breeding pea plants, we’ve been learning about our genomes. In 1953, Watson, Crick and Franklin described the structure of the molecule that makes up our genomes: the DNA double helix. Then, in 2001, scientists wrote down the entire 3-billion letter code contained in the average human genome. Now they’re trying to interpret that code; to work out how it’s used to make different types of cells and different people. The ENCODE project, as it’s called, is the latest chapter in the story of you. — Nature.com
