RNA strands are shorter than DNA strands. RNA sometimes forms a secondary double helix structure, but only intermittently. DNA is a much longer polymer than RNA. A chromosome, for example, is a single ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

The parent strand and the new strand then re-coil into the usual double helix structure. While DNA is exposed in a single-stranded form, certain sequences can fold into unusual DNA secondary ...

B-DNA is the most common form of DNA and has a right-handed double helix structure. A-DNA forms in a shorter, right-handed double helix. The function of this form is to protect DNA. DNA will ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Her colleague Maurice Wilkins was independently pursuing DNA’s structure, and she had grown so miserable there, largely because of their rivalry, that she had found a position at another university.

Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...

This new study provides definitive evidence about how these secondary DNA structures ... stalled eukaryotic replisome structure reveals helical inchworm DNA translocation, Science (2025).

Researchers identify physical factors that determine how quickly two DNA strands can come together, resolving a decades-old conundrum. Nanoscientists and theoretical physicists at UNSW Medicine ...
