Our DNA is constantly being packed and unpacked. And there is a good reason for this: depending on its packing state, it performs different functions in the cell nucleus. For most of its life – this ...

A major advance in cell biology has revealed how our cells safeguard their genetic material during one of the most vulnerable moments in their life cycle. The study identifies a specific protein ...

(Nanowerk News) If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged. When it is time for cell ...

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 ...

A prevailing belief that the 3D structure of DNA disappears completely when cells divide has been overturned. Rather than DNA fully unwinding into a flat configuration, some regions of chromosomes ...

A major advance in cell biology has revealed how our cells safeguard their genetic material during one of the most vulnerable moments in their life cycle. The study identifies a specific protein ...

If DNA bridges are not eliminated during cell division, chromosomes may be abnormally segregated, leading to genetic issues such as cancer. For the first time, the mechanism of a protein that serves ...

Week 3 of pregnancy marks a crucial phase when your baby’s genetic blueprint begins to guide development. Although DNA is ...
