Guided by the work of Rosalind Franklin, James Watson and Francis Crick discovered the the twisted-ladder structure of DNA in 1953, a finding that gave rise to the modern field of molecular biology.

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 ...

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 ...

A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. This new structural and ...

Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...

There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there are ...

Researchers have developed a new fluorescent label that gives a clearer picture of how DNA architecture is disrupted in cancer cells. The findings could improve cancer diagnoses for patients. Their ...

DNA Full Form: The full name of DNA is Deoxyribonucleic Acid. This molecule holds the complete genetic code of living organisms. The name “Deoxyribonucleic Acid” reflects its part: “Deoxy” points to ...

For James Watson, DNA was everything — not just his life's work, but the secret of life itself. Over his long and storied career, Watson arguably did more than any other scientist to transform a ...
