Which brings me to the final dénouement: pulling out the protocol's instructions, pipette in hand. Immediately, I was overcome with the same terror that cookbooks instill in me.

Clear like "totally transparent", or clear like "I can see the DNA goop"? I stumbled along, undoubtedly compounding errors at each step.
