Topic Area: Nervous System - Resting Membrane Potential 1. Explain the resting membrane potential by discussing: What function does Na+/K+ ATPase membrane pumps play in the membrane potential?

2. Describe the mechanism for the propagation of an action potential: your answer should include all the phases, ions, and type of ion channels involved in each phase, direction of movement of ions, and which refractory period occurs during which phase.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
