Chapter 12, Problem 23RQ
Summary Introduction
To determine: The way in which fibres present in different types of muscles generate ATP.
Introduction: The key feature of muscle physiology is the use of ATP by the fibers of muscles. Muscles need energy continuously. The muscle fibres require energy during contraction for the movement of the cross-bridge. They need energy during relaxation for the pumping of calcium ions back into the sarcoplasmic reticulum. Finally, the sodium ions and potassium ions are restored to their respective intracellular compartments after excitation-contraction coupling.

From your previous experiment, you found that this enhancer activates stripe 2 of eve expression. When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?
What experiment could you do to see if the maternal gene, bicoid, is sufficient to form anterior fates?
You’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene.
Describe an experimental technique you would use to find out where this particular eve enhancer is active.
