![]() ![]() According to their findings, DNA replicated itself by separating into individual strands, each of which became the template for a new double helix. On the morning of February 28, they determined that the structure of DNA was a double-helix polymer, or a spiral of two DNA strands, each containing a long chain of monomer nucleotides, wound around each other. LISTEN NOW: HISTORY This Week Podcast: The DNA Debate California chemist Linus Pauling suggested an incorrect model at the beginning of 1953, prompting Watson and Crick to try and beat Pauling at his own game. ![]() ![]() ![]() In the early 1950s, Watson and Crick were only two of many scientists working on figuring out the structure of DNA. Though DNA-short for deoxyribonucleic acid-was discovered in 1869, its crucial role in determining genetic inheritance wasn’t demonstrated until 1943. The molecular biologists were aided significantly by the work of another DNA researcher, Rosalind Franklin, although she is not included in the announcement, nor did she share the subsequent Nobel Prize award for it. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes. On February 28, 1953, Cambridge University scientists James D. ![]()
