The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a ...

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.

More complex and not answered at the time was the question of why there were two forms. What was the nature of the less-hydrated fibers that produced the better-oriented and crystalline A-form, which ...

The most famous image to emerge from 20th-century biology is the deoxyribonucleic acid (DNA) double helix, illustrating the structure of the gene, life’s genetic material. Credit for the discovery of ...

Few science books have managed to make readers laugh, gasp, and learn all at once, but The Double Helix by James D. Watson does just that. Published in 1968, this iconic memoir pulls readers straight ...

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 ...

DNA is more than just the secret of life--it is also a versatile component for making nanoscopic structures and devices The year 2003 witnessed the 50th anniversary of the discovery of DNAs ...
