comment How can I compare rates of evolution for two sets of proteins?
@terdon: if you want to compute ka/ks ratios, you need to look at the nucleotide sequences, no?

comment How can I compare rates of evolution for two sets of proteins?
The eggNOG database also contains alignments for protein families, but these are on the amino acid level. So you would still somehow have to go back to a nucleotide alignment, which I'm not quite sure how to do. :-/ Might be a good question to ask on BioStar with its larger bioinf audience.

are you working on species that have already been sequenced (for which you might info in databases), or do you have novel sequencing data?

comment Why do living organisms replicate itself or procreate
Yes, reproduction is part of the definition of life. However, this doesn't mean that a sterile animal doesn't live.

comment Multiple sequence alignment - how to align everything to 1 gene sequence?
Which kind of result do you want to have? One alignment with three sequences, or two pair-wise alignments? If the former, what would you do if one of the 1000bp sequences causes a gap in the reference sequence?

comment What is the difference between orthologs, paralogs and homologs?
Another pet peeve: homology is qualitative, not quantitative. So saying "significant homology" or "weak homology" is just wrong.
