3 ) Formulate an evidence-based explanation regarding how the composition of deoxyribonucleic acid (DNA) determines the structural organization of proteins.

a. Obtain and evaluate experiments of major scientists and communicate their contributions to the development of the structure of DNA and to the development of the central dogma of molecular biology.

b. Obtain, evaluate, and communicate information that explains how advancements in genetic technology (e.g., Human Genome Project, Encyclopedia of DNA Elements [ENCODE] project, 1000 Genomes Project) have contributed to the understanding as to how a genetic change at the DNA level may affect proteins and, in turn, influence the appearance of traits.

c. Obtain information to identify errors that occur during DNA replication (e.g., deletion, insertion, translocation, substitution, inversion, frame-shift, point mutations).

Subject: Science (9 - 12)
Title: The Secret Code of Life

This interactive website allows students to examine the process of how each protein is coded for in the deoxyribonucleic acid (DNA) which hold the “The Secret Code of Life”. Students are able to manipulate models to explore transcription to demonstrate how complementary nucleotides bind to ensure a correct copy. Next, students are able to manipulate and observe, step by step, the process of translation. Students are then able to observe the folding of proteins and experiment with a protein model simulation. Lastly, students are able to apply mutations to a simulated protein sequence to observe what happens to the protein.

This activity was created as a result of the GAP Resource Summit.
