What did Francis Crick discover?

Structure of the RNA

Structure of the DNA

Francis Crick is renowned for his pivotal discovery regarding the structure of DNA, which he elucidated in collaboration with James Watson. In 1953, they proposed the double helix model, revealing how the DNA molecule is composed of two strands that twist around each other, with bases pairing in a specific manner (adenine with thymine, and cytosine with guanine). This finding was groundbreaking as it not only provided insight into the genetic code but also laid the foundation for modern genetics and molecular biology, influencing how biological information is stored, copied, and transmitted in living organisms. The other choices do not align with Crick's key contributions; his work focused specifically on DNA, making this the correct response.
