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 Which C. elegans would be appropriate for general study?
What question do you want to answer? The "appropriate" decision will depend on what exactly you want to investigate. What conclusions will you want to draw from your research?

comment Does this “fleeing spiders leaving fields of webs” phenomenon have a name?
I doubt it will be called anything specific. It's just spiders fleeing a flood like any other animal.

comment BLASTn vs ORF tools
@Raghavakrishna I'm sorry but I still don't understand. The details always depend on what you're actually doing. If BLAST gives you a hit, then that's a hit. Whether or not that is biologically relevant is another question and I can't answer that unless I know what question you are asking.

comment BLASTn vs ORF tools
@Raghavakrishna why would they be false positives because they align against the - strand?

comment Finding proteins in DNA sequence
@Raghavakrishna I still don't understand what you're asking. Sequencing projects sequence one strand and call that the + strand and then extrapolate the sequence of the - strand. If you have a question about this, please ask a new question so you can explain it clearly and get a full answer.

comment Finding proteins in DNA sequence
@Raghavakrishna what do you mean? What method? If you mean the two tools I mentioned, exonerate searches both strands by default and genewise does so if you give it the -trev flag.

comment Why aren't introns found on the ends of pre-RNA?
@user137 exactly. Being an exon has nothing whatsoever to do with being a coding exon. You even have transcripts that don't code for protein at all but that contain introns regardless.

@user137 (and Armatus) UTRs are exons, some of them even contain introns and are spliced just like coding exons.

comment Degenerate Alignment Analysis
This would be much easier to answer if you gave us some more context. Presumably you are referring to sequence alignments but where did you read the term? What was it referring to?

comment Did Darwin ever reach the conclusion that selection will remove variation?
I don't think you can simply ignore mutation like that. Each generation may have its variation reduced by selection but novel variants will also pop up through mutation and copy errors. We'd have to take both rates (that of loss and that of gain of variation) into account to answer this.
