The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

On the left side, in vitro preassembled DNA circuits are delivered into living cells. Alternatively, on the right side, RNA pregates are autonomously transcribed from the chromosome or plasmids to be ...

“The laws of inheritance are quite unknown,” Charles Darwin acknowledged in 1859. The discovery of DNA’s shape altered how we conceived of life itself. The X-ray crystallography by Rosalind Franklin ...

For James Watson, DNA was everything — not just his life's work, but the secret of life itself. Over his long and storied career, Watson arguably did more than any other scientist to transform a ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...
