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.

comment Why was disease transfer to the Americas one-way?
I find this very hard to believe (though I know absolutely nothing about it so I am likely wrong). Surely at least the parasites were a problem for the colonists! We know there are all sorts of parasitic pathogens endemic to the Americas, none of which would be familiar to the European immune systems. Weren't they an issue?
