DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

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

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

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

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...

As people grow older, their immune systems do not simply slow down, they often become locked into a simmering, ...
