This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

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

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

Researchers created the most detailed maps yet of the genome’s three-dimensional organization using human stem cells and ...

A team of researchers has generated one of the most detailed 3D maps of human chromosomes, cataloging over 140,000 DNA looping interactions.

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 ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...
