Textbook Question
Chapter 4, Problem 9P
Suppose that you centrifuged a transfer RNA molecule to equilibrium in an alkaline CsCl gradient, as described in Problem 7. What result would you expect?
7. For some DNAs, it is possible to separate the two strands, after denaturation, in a CsCl gradient.
a. What property of any DNA determines where it will band in a CsCl?
b. What kind of DNA might have two strands that differ sufficiently in this property that they could be separated after denaturation?

When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
