comment Hiding identical sequences in NCBI web interface
well, just take one sequence from each cluster! if you download the UniRef databases, you actually get the non-redundant set.

comment Local storage of NCBI database in MongoDB
This question appears to be off-topic because it is about pure bioinformatics implementation issues, not biology. Also: why would you want to use MongoDB, given you just heard about it and don't know the advantages?

comment What is the close and related genome used for in Gene models?
can you please be more specific, like what species you have in mind and if you are talking about RNA or DNA?

comment “selective pressure” or “selection pressure”?
From a grammar standpoint I would think that "selection pressure" is a compound noun. But I was looking for a biological answer, if one is more appropriate than the other.

comment Draw simplified phylogenetic tree for kids
you can use itol.embl.de to get trees based on the NCBI taxonomy, but you'd have to use a graphic program to make them prettier

Have you seen this question on stats SE: stats.stackexchange.com/questions/18833/… ?

comment How to calculate extent of Sequence similarity
very interesting ... the standard methods all work on linear values, and not angles. Is the pattern "30 60 90" similar to "120 150 180"? (I.e. do you only care about relative movement, or also about the actual direction?)

comment What is the difference between these worms: Caenorhabditis elegans and Eisenia fetida?
The time of divergence within the nematodes is already estimated to be >500 million years timetree.org/pdf/Blaxter2009Chap28.pdf -- so the divergence of annelids and annelids must be even earlier

comment Are SLC52A2 and GPR172A really the same?
the functions just seem to be so diverse that I have a hard time believing it... but you never know, I guess

comment Can one die from pain?
great answer! though the fire/smoke analogy is not so apt: "50–80% of fire deaths are the result of smoke inhalation injuries" en.wikipedia.org/wiki/Smoke_inhalation

comment When a Lysosome's bonding sites all get bonded to, what is the most resource and energy efficient way to handle the used Lysosome?
Enzymes are catalysts, i.e. by definition they don't get used up. More info on "cellular garbage disposal" can be found here: en.wikipedia.org/wiki/Lysosome

comment Information Gene HBA2
you could also use wikipedia as a starting point: en.wikipedia.org/wiki/Hemoglobin,_alpha_2 for many genes this will give you already a good overview and links to sources

comment Comparing BLAST and the Smith-Waterman algorithm
BLAST uses a heuristic, but mainly to cut down the time spent looking for homologs, not to produce better alignment. So BLAST is not more accurate than S-W, but often times accurate enough.

comment Are there more descriptive ways of naming genes and gene interactions?
@AlexStone: there are pathways that can be given a nice name, e.g. genome.jp/kegg/pathway.html -- but even then there will be more functions to the pathway than what can be encapsulated in the name
