Elected moderator on Unix & Linux. Feel free to @ping me in chat if there's anything I can help you with.

I am a computational biologist with a background in biology, not computers. My PhD work was on gene prediction and comparative genomics but my current research is in systems biology, specifically protein-protein interaction networks.

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?

comment Why is cold water more refreshing than warm water?
Hi and welcome to the site. First of all, we expect answers here to be backed by references. That said, this does not answer my question. I am asking why cold water feels more refreshing, what is the biological method through which this feeling is expressed.

comment How can I align more than 2 sequences locally?
More than you might think. The NCBI blast lets you set things like e-value, gap penalty, match/mismatch scores, low complexity filtering. That's more than enough for 99% of uses.

comment How can I align more than 2 sequences locally?
The various web-based BLAST tools are basically a GUI for BLAST.

comment How much usable protein(/amino acids) for the human body is there in plants VS meat? (Percentage wise)
What plants? What meat? How much of either? Under what conditions were the plants grown/the animals raised? Percentage of what? Of available amino acids? Of total protein? Of net weight? Dry or wet? This is really too broad to be answerable.

comment How did bullying arise evolutionarily?
@AliceD please never ever suggest cross-posting. We try very hard to avoid duplicating questions on multiple SE sites. If a question can fit on both sites, it should be tweaked to ask for different aspects of the issue based on each site's scope, not repeated.
