DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

Centuries-old genetic material can solve historical mysteries, from lost species to what killed Napoleon’s army.

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Sediment DNA also traces life outside the cave. Predators dragged prey into sheltered chambers, humans left waste behind. By ...

I have spent years covering discoveries that nudge our origin story around the edges, but the sequencing of DNA from one of ...

Cornell researchers have found that a new DNA sequencing technology can be used to study how transposons move within and bind ...

A closeup look at colibactin’s structure reveals chemical motifs that guide its mutation-wreaking “warheads” to specific stretches of DNA.
