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 What is the smallest oligocelluar organism?
@har-wradim hello and welcome to the site. There is no such thing as "the correct answer" on the stackexchange network, the OP chooses to accept whichever answer suits them and that answer is, by definition, the "best". It may be wrong or incomplete but if the OP feels it answers their question then that's that. As for dicty, the cool thing is that it exists and can live as both a single cell and as a multicellular aggregate. The worm cannot and the zygote is an "unfinished" animal, they are completely different.

@draks... thanks for the accept but there are probably more extreme examples.

comment What is the smallest oligocelluar organism?
@Chris well yes but dicty cell counts go from 1 to 100.000 while the worm is always at 956. The interesting part is that dicty exists as a single celled organism as well.

comment Effects of smoking tobacco compared to inhaling other smoke
@Oreotrephes the point is that if you ingest the same quantities of any of these types of smoke, they will cause serious health issues. Of the three, I expect cigarette smoke to be the least noxious.

comment Effects of smoking tobacco compared to inhaling other smoke
Umm, not at all? What makes you think tobacco smoke is more dangerous? If anything, I would expect tobacco smoke to be the least dangerous of the three.

comment How would constantly growing nails have aided early human?
My guess is that they would work very much like the claws of other animals. Dogs for example will trim their nails by walking around outside. Dogs that live in houses need to have them cut.

comment Codon alignment via Python?
I am quite familiar with it, thanks :). I did my PhD on comparative genomics and reconstructing evolutionary histories, I've done more alignments than I care to remember. You need to know whether two codons are synonymous or not in order to get the dN/dS but not necessarily to translate them, it's just an easy way to check. Anyway, using my dict suggestion this is pretty trivial. Feel free to @ping me in Biology Chat if you need more help with it.

comment Codon alignment via Python?
This question appears to be off-topic because it is about programming and not biology. Bioinformatics questions are on topic here if they are about the underlying concepts, you are asking a very technical issue whose answer will be code.

comment Codon alignment via Python?
Anyway, I would simply create a hash (a dict I believe they're called in Python) that links each amino acid to its codon. Then, once you have your alignment, read it and use the dict to translate back to the original codons inserting the gaps as you find them.

comment Codon alignment via Python?
You can do that easily enough from the DNA sequence, no need to translate. Just align and read the codons from the alignment. You seem to be complicating your life needlessly. That said, this is probably too computer geeky for this site and you would be better off asking on biostars.

Why don't you simply align the nucleotide sequences in the first place? Just use any alignment software.

comment Studying the fruitfly nervous system
Please narrow this down a little, you could fill libraries with the sources of info on this little fly. What exactly are you after? Text books? Reviews? Original research? On what? Anatomy? Nervous system? Immune system? Sex determination?
