In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

DNA stands for Deoxyribonucleic Acid, the molecule that carries the genetic code of all living things. It’s found in every cell and determines everything from your looks to your body functions. In ...

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 ...

DNA is the genetic material used by every living organism. But, in a few edge cases, the four bases of DNA—adenine, thymidine, cytosine, and guanine—undergo chemical modifications. And in viruses, ...

Cockayne syndrome (CS) is a rare disease that causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay. A new study by researchers from the ...

The findings may have important implications for diseases linked to mitochondrial dysfunction. A newly identified form of DNA damage inside mitochondria, the small structures that supply energy to our ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...
