In addition, the annotated genome can be browsed in an environment that supports comparative analysis with the annotated genomes maintained in the SEED environment.
In particular, microsatellites, a class of highly polymorphic repetitive sequences considered by most to be neutrally evolving junk DNA that is too labile to be maintained in distant species, have not been comprehensively studied in a comparative genomic framework.
Comparative mapping data indicate that these imprinted clusters are maintained in synteny in mice, and apparently in cattle and pigs, suggesting that the maintenance of such syntenies is requested for achieving a normal placental physiology in eutherian mammals.
Further comparative genomics studies report that at least 20% of gene duplicates have been maintained in zebrafish, often by divergence of regulation between the duplicate loci that imposes an evolutionary constraint on both genes [ 22].
Our comparative study reveals that genes essential for physical (e.g. engulfment of the offspring cell) and regulatory mechanisms (e.g. alternative sigma factors and intracellular communication) have been maintained in a live-offspring-bearing cell.
It's comparative simplicity made it cheap to manufacture as well as reliable and easy to maintain in the field.
The Panamera is roughly $20,000 cheaper, however, so to maintain its comparative advantage in this not-so-hypothetical marketplace, a Karma would have to rely on its purely electric range and comparative rarity on the road.
UNICEF maintains its comparative advantage in health, nutrition, education, water and sanitation, child protection and social policy in its support to the Government of Iraq.
Maintaining its comparative advantage in health, nutrition, education, water and sanitation, child protection and social policy, UNICEF supports the development of child friendly policies, building the capacity of institutions that deliver essential services to children and convening all duty bearers to realize the full rights of Iraqi children.
As for international trade, there are some who say that in today's globalized world, labor must be repressed so that labor costs remain low and countries with low labor costs maintain their comparative advantages (if in fact they had them in the first place).
