01 / The world before
The molecular structure of genetic material was unresolved.
02 / The discovery
X-ray evidence and molecular modeling supported the double-helix structure.
03 / The people
Franklin, Gosling, Wilkins, Watson, Crick and others.
04 / The obstacles
Attribution and access to evidence shaped the history of recognition.
05 / The world after
The structure helped frame research into copying and inheritance.
06 / Why it still matters
Modern genetics rests on collaborative evidence.
