DNA - The Double Helix
... In 1953, James Watson and Francis Crick established the structure of DNA. The shape of DNA is a double helix which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. Color all the phosphates red (one is labeled with a "p ...
