What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing ...

Estrogen is known as an important hormone, and it can control many functions by regulating the activity of hundreds of genes.

Research reveals that five DNA letters can switch chromatin between fluid and solid-like states, influencing gene ...

Researchers have identified the specific structural loops in G-quadruplex DNA that allow it to act as a chaperone, preventing ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

DNA origami cages constrain individual proteins toward preferred orientations on electrodes, dramatically improving ...

If stretched out, human DNA would be about 2 meters long. For this long strand to fit inside the cell nucleus, which is about 0.01 mm in size, it must be tightly folded. DNA wraps around proteins call ...
