comment Why reference genome is a reference?
@vajra78 it probably never will actually. These differences are irrelevant for most studies. You almost never care about individual genotypes, not unless this is a medical issue involving a specific individual. The point here is alignment and that is not affected by such small changes. Studies at the species level (looking at evolution or genetic regulation etc) rarely, if ever, need to take into account the intra-species variation.

comment Can bioluminescence be used for cancer or tumor detection?
Ah OK, that makes more sense. I was having trouble imagining how a promoter could be completely specific to tumor cells.

Huh, I stand corrected, thanks. I didn't know there were tumor-specific promoters.

comment Can bioluminescence be used for cancer or tumor detection?
What would a cancer specific promoter be? You could target a particular cell type, but how would you distinguish between tumorous and healthy? They have the same promoters. You could, perhaps, use promoters that are only active in proliferating cells but that limits the usefulness of the approach. More importantly, how would you detect the bioluminescence in, say, the liver?

@Lefty in that case, please edit your question so the actual question being asked is clearer.

What kind of organism? Multicellular or unicellular? If the former, what cell? A random cell of a multicellular organism? A gamete?

comment Why is cold water more refreshing than warm water?
Ah, so you're suggesting that the difference in taste is down ti the relative concentrations of these receptors, right? OK, any ideas on why one would feel more refreshing (which, presumably, translates to more hydrating) than the other?
