During DNA replication, the classic double helix can temporarily rearrange into an alternative structure known as a DNA three ...

By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered that strand separation—the essential process a "resting" double helix ...

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 ...

Artist's impression of the DNA double helix structure. We are increasingly learning that these DNA strands can be unzipped to form new structures, affecting which genes are turned on and off in a ...

New research predicts the location of DNA sequences that can form structures besides the canonical double helix — non-B DNA — in the recently released telomere-to-telomere genomes of the great ...

Fifty years ago, James Watson and Francis Crick -- in a true "eureka" moment -- identified the double-helix structure of the molecule DNA, informing genetic research for decades to come. Their ...

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 ...

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and ...
