In 1953, Francis Crick and James Watson discovered the famous double helix shape of DNA! π§¬
They noticed that DNA looks like
a twisted ladder, with rungs made of bases called adenine, thymine, cytosine, and guanine. These bases pair up perfectlyβA with T, and C with G! This discovery was groundbreaking because it helped scientists understand how traits are passed from parents to kids. π
Their work laid the foundation for modern genetics and made it possible to study DNA in detail. π§ͺ
