SKILL EXERCISES POST-ACTIVITY 1. The E2F family of transcription factors is important in regulating the cell cycle and has a role in cancer. These DNA binding proteins have conserved helix-turn-helix motifs that interact with DNA (NOTE: The DNA is represented as a stick diagram, whereas the protein is represented as helical ribbons.) Consider the protein a helix indicated by the arrow. This helix is approximately 16 amino acids in length and runs along side the DNA. Suggest a sequence for this 16 amino acid helix and provide a justification for your answer. Picture from Meinhart, A. et al. J. Biol. Chem. 2003;278:48267-48274 (used by permission). DNA View this skill exercise as an opportunity to practice scientific argumentation. Therefore the justification will be the most important aspect of your answer.
