The Discovery of DNA's Structure:

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 ...

Study explores limits of DNA structure and function, may expand use of modified DNA in medicine

A team led by Professor Michal Hocek at IOCB Prague has explored the limits of the structure and function of DNA and successfully pushed forward known boundaries. Their latest research has just been ...

In 1953, scientists pieced together a twisted molecule, and DNA finally had a shape

Scientists uncovered DNA's double helix structure in 1953. James Watson and Francis Crick proposed the model. It explained ...

Unravelling DNA’s structure: a landmark achievement whose authors were not fairly credited

Seventy years ago, two male scientists, Francis Crick and James Watson, proclaimed they had discovered the secret of life: the structure of DNA. Since then, history has acknowledged how Rosalind ...

Structure of the TnsB transposase-DNA complex of type V-K CRISPR-associated transposon

CRISPR-associated transposons (CASTs) are mobile genetic elements that co-opted CRISPR-Cas systems for RNA-guided transposition. Here we present the 2.4 Å cryo-EM structure of the Scytonema hofmannii ...

Correction: Rosalind Franklin's crucial contribution to the discovery of DNA's structure

A piece that aired on NPR this week about the discovery of DNA's structure neglected to mention the significant contribution of Rosalind Franklin to that scientific milestone. And now some important ...

Density and structure of DNA immobilised on gold nanoparticles affect sensitivity in nucleic acid detection

Gold nanoparticles (AuNPs) are used as colorimetric biosensors that, combined with immobilised single-stranded DNA (ssDNA-AuNPs), can be used in genetic diagnosis because of their rapid and ...

DNA repair enzyme uses one-dimensional sliding to detect key sites, researchers reveal

DNA is the blueprint of the human body. However, tens of thousands of DNA lesions occur in our bodies every day. In particular, if "apurinic/apyrimidinic sites" (AP sites, damaged sites where one ...

James Watson, Who Co-Discovered DNA Structure, Dies at 97

James Watson, the scientist who became famous for helping discover the structure of DNA in 1953 and notorious decades later for suggesting that Black people are intellectually inferior to whites, has ...
