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 Domains in cell membrane
@WYSIWYG not really. All I know of lipid rafts is what I recall from the relevant classes I took 10 years ago in university. I'm not really competent to elaborate.

comment Do “Giraffe Weevil” males build Nests
Are these photographs of the specimen you found or are they taken from the web? If the latter, the likeliest explanation is that what you found looks very similar but is a different species.

comment Why is the DNA codon table “equal” to the RNA codon table
@Sosi no, the double strands are essential for many things including i) DNA replication ii) error repair (the "right" sequence can be inferred from the opposite strand iii) most importantly, genes can be found on both strands. The sense/antisense is only with respect to a given gene. What is the sense strand for geneX can be the antisense for geneY.

comment Incestual Reproduction in Animals
Since inbreeding can lead to greater chances of genetic abnormalities, it seems reasonable that individuals who avoid it would be selected for in the long run but I don't know of any studies on this.

comment what the best E-value cutoff in the miRNA homology search
Absolutely. Your parameters sound fine. I just wouldn't use an evalue of 10 as a way of determining whether a hit was interesting. I'd leave it at 10 or higher to be sure to get everything and then ignore it and filter on other things as you suggest.

comment Are there any known mutual symbiotic relationships that has more than two agents?
I'm not entirely sure that this constitutes symbiosis. It's a very valid point and +1 but I wonder if someone working in the field would consider it so.

comment what the best E-value cutoff in the miRNA homology search
10? Really? I haven't worked with miRs but 10 seems extremely high. In fact, working on short nucleotide sequences, I wouldn't recommend using the evalue at all. I'd go for plain %id and % coverage instead.

comment Find protein homologs with BLASTp
What species are you comparing? How distant are they? If close enough, "real" homologs should be able to form a single HSP spanning most of the target sequences.

comment Why don't fish groom each other?
@VatsalManot yes, but I think it's applicable to all. In order to be able to eat parasites, you need to be small enough to get at them. Presumably, if you're the same species, you will be too big. Still, as I said, this is pure speculation.
