A fleeting DNA fold called i‑DNA can switch cancer‑related genes on and off, revealing a hidden structural weak point that ...

相同組換えは、DNA分子間の遺伝情報の交換を可能にするDNA修復機構だ。RecAというタンパク質がその過程を取り仕切る様子が、構造解析で明らかにされた。 我々生物の染色体は、常に、ゲノムの完全性が損なわれかねないようなDNA損傷を与える、紫外線や ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA – its genome – and segregate it equally ...

Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence ...
