comment NADH vs. NADPH: Where is each one used and why that instead of the other?
Great use of the link to the chapter - I wish more authors did this.

Besides mixing fluids of different viscosities, are vortexers necessary for any other lab operations?

Vortexing is called for when one or more of the fluid samples is more viscous than water? For instance (as you suggest), 100% glycerol is 1000x more dynamically viscous than water, hence the need for a vortexer to mix water and glycerol well (wolframalpha.com/input/…).

comment What is the criticality of the ribosome binding site relative to the start codon in prokaryotic translation?
It was an interesting question to investigate and I enjoyed learning about it. I hope more well-posed and provocative questions are asked here and that users react to them by actually going out and reading up on the primary literature. Looks like that happens occasionally. Cool.
