Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Structural biologists at the University of Wisconsin-Madison today published cryo-electron microscopy structures of the complete bacterial DNA replication restart complex — a molecular machine that le ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed. The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a ...

Researchers have mapped 50,000 of DNA's mysterious "knots" in the human genome. The innovative study of DNA's hidden structures may open up new approaches for treatment and diagnosis of diseases, ...

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.

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

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 ...
