The discovery of DNA is often attributed to James Watson and Francis Crick, who published their groundbreaking model of the double helix structure in 1953.

However, it's important to remember that many other scientists contributed to the understanding of DNA, including:

* Rosalind Franklin: Her X-ray diffraction images of DNA were crucial for Watson and Crick's model.

* Maurice Wilkins: He worked with Franklin and provided important data.

* Erwin Chargaff: His rules on the base pairing in DNA were essential for understanding the structure.

So, while Watson and Crick are most known for the discovery, it was a collaborative effort of many brilliant scientists.
