Adenine was first discovered in 1885 by the German physiologist Albrecht Kossel. He isolated adenine from the pancreas of oxen and named it "adenine" derived from the Greek word "aden," meaning gland.

The process begins by unzipping DNA's ladder-like structure, resulting in two strands called the leading and lagging strands. A molecular construction crew then assembles the missing halves of the ...

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without any template to guide them, a behavior the team calls “doodling.” Published ...

The findings, published in Science Advances, reveal a previously unrecognized mechanism to protect DNA replication and genome stability that could lead to new treatments for some cancers. "This study ...
