Questions
Belоw is the mutаtiоn in the limb enhаncer fоr sonic hedgehog аnd the phenotype to which it leads.... Be sure to answer all 3 parts and clearly label each part of the answer. Part 1: What is the normal role for sonic hedgehog during anterior-posterior axis patterning of the limbs (2 pts)? Part 2: Based on the figures above, describe how this mutation can lead to such a dramatic alteration. Your description should: 1) indicate if the mutated region of the enhancer is normally an activator or repressor of Shh and a brief description WHY you say this, and 2) include a description of how this nucleotide mutation change alters gene expression in this manner. (4 points) Part 3: Sonic hedgehog is a very important morphogen during development of many tissues. Briefly describe why this particular mutation does not affect the overall health of the organism beyond the limb phenotype shown (3 points)
