As imaging tools continue to get more sophisticated, researchers have been able to actually watch biological processes as they are happening in live cells. Scientists have now visualized loops of DNA ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

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 ...

Estrogen is known as an important hormone, and it can control many cellular and bodily functions by regulating the activity of hundreds of genes. Scientists have now learned more about how estrogen ...

DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

James Watson, a renowned molecular biologist and one of the Nobel Prize winners for discovering the structure of DNA, died Thursday after a brief illness, according to a statement from his former ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s genetic code ...
