Researchers mapped RNA fragments embedded in human DNA, revealing a new genomic layer called the "ribome" that may shape gene activity.

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

A new study by researchers at the Perelman School of Medicine at the University of Pennsylvania reveals that the ...

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 ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...

An important specialty in this field—and a signature area of study at the University at Albany's RNA Institute—is DNA nanotechnology, wherein the base pairs that comprise DNA molecules are manipulated ...

A molecular illustration of the crowded interior and cell envelope of Escherichia coli. (David S. Goodsell, The Scripps ...

Seventy years ago, two male scientists, Francis Crick and James Watson, proclaimed they had discovered the secret of life: the structure of DNA. Since then, history has acknowledged how Rosalind ...

In a world-first study, we have revealed and analysed remarkably preserved fragments of ancient DNA from the skin of a woolly mammoth. For the first time, we’ve been able to understand how the genetic ...
