Animation of DNA’s knot-like i-motif structure the team mapped in 50,000 locations in the human genome, concentrated in key functional areas including regions that control gene activity Credit must be ...

Water molecules surround the genetic material DNA in a very specific way. Scientists have discovered that, on the one hand, the texture of this hydration shell depends on the water content and, on the ...

A new study published in Nature Structural & Molecular Biology reveals how the fundamental enzyme called DNA polymerase delta operates during DNA replication, making a copy of the genetic code that ...

They were hardly modest, these two brash young scientists who in 1953 declared to patrons of the Eagle Pub in Cambridge, England, that they had "found the secret of life." But James Watson and Francis ...

Here's NPR correspondent Joe Palca, from a 1993 broadcast, to commemorate the anniversary of the discovery of the structure of DNA. Sponsor Message : [POST-BROADCAST CLARIFICATION: This story, which ...

Life on Earth can scarcely escape the ultraviolet radiation of sunlight, which catalyses covalent linkages between adjacent pyrimidines in DNA 1. The resulting pyrimidine dimers are barriers to most ...

What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic acid or ...

DNA aptamers are powerful molecular tools in biosensing, bioimaging and therapeutics. However, a limited understanding of their tertiary structures and binding mechanisms hinders their further ...
