can you answer 1-3 pls 1. Study Power Point for Chapter 18. What gene is mutated in Drosophila (fruit flies) that are missing a heart and die in early embryogenesis? What is the name of the human gene with similar sequence that causes heart defects in infants? 2. For Lou Gehrig disease, what gene is affected? 3. What did we find out about ALS using fruit flies? (describe in detail: the symptoms and the weird reading frames and the little polypeptides that result from the weird reading frames and how they contribute to the disease).
