By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Although DNA is often found as a single-stranded polynucleotide, it assumes its most stable form when double stranded. Double-stranded DNA consists of two polynucleotides that are arranged such ...

For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals ...

(Remember, DNA is almost always in a double-stranded helical form.) Furthermore, RNA contains ribose sugar molecules, which are slightly different than the deoxyribosemolecules found in DNA.

Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. .

For DNA to be copied, the DNA double helix must open up, and the resulting single strands—each of which serves as a template for building a new, second strand—are vulnerable to breakage. Or ...

The final DNA strand contains close to 1,700 nucleotides. When the researchers heated and cooled their DNA strands in a test tube, each one folded in on itself and snapped into a virus-size ...
