Deoxyribonucleic acid (DNA) replication is fundamental to life, yet the precise mechanics of how helicases unwind the genome for replication remain unclear. A recent study published in Nature used ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

In recent months I’ve highlighted two excellent iPad apps by OnScreen Science that center around a 3D model of DNA. For the sake of completeness, let me now mention the third and final member of the ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

Scientists have found that non-coding 'junk' DNA, far from being harmless and inert, could potentially contribute to the development of cancer. Their study has shown how non-coding DNA can get in the ...

A new model offers a possible solution to the scientific question of why neutral sequences, sometimes referred to as 'junk DNA', are not eliminated from the genome of living creatures in nature and ...
