WebThe Double-Helix Model. A double helix looks like a twisted ladder. In the double-helix model of DNA, the two strands twist around each other like spiral staircases. The double helix accounted for Franklin’s X-ray pattern and explains Chargaff’s rule of base pairing and how the two strands of DNA are held together. WebSep 4, 2024 · DNA. DNA codes for proteins, controlling which and how many proteins are made. Proteins are made from strings of amino acids, and the structure and function of a protein depends on the exact sequence of these amino acids - DNA controls this protein structure by determining the exact order in which amino acids join together.
