In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

In both physics and chemistry, the mesoscopic scale refers to the length scale on which the properties of a material or phenomenon can be studied, without entering into a discussion about the behavior ...

Researchers at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

Rosalind Franklin’s role in the discovery of the structure of DNA may have been different than previously believed. Franklin wasn’t the victim of data theft at the hands of James Watson and Francis ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process.

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 ...
