Because two paired appendages are unique to gnathostomes and cartilaginous fish occupy the earliest branch of the gnathostome lineage the study of the cartilaginous dogfish may provide insight into how animals have acquired morphologically diverse paired appendages.
This is plausible in view of the mechanism of recombination in HIV-1, in which the likelihood of producing mosaic genomes increases with the number of diverse pairs of RNA strands that get packaged into a viral particle.
As shown in supplementary fig. S5, Supplementary Material online, when the genome-wide sequence divergence is 0.0021 (i.e., the upper bound divergence used in the determination of nonvertical genes), there are only 26.6% identical genes between all genomes, whereas there are 63.5% identical genes between the most diverse genome pair within an ST (FAM18-S0108).
One prediction of 'ecological speciation' models is that pairs of populations feeding on distinctive host plants will be more genetically diverse than pairs feeding on the same host (Funk 1998).
[This observed reduction could also partially reflect an effective reduction in the average count of diverse conformer pairs per compound considered, because not every compound considered will have ten diverse conformers associated.
Genome analyses of interesting gene clusters such as secretion system genes, toxin production genes, bacterial QS genes, and CRISPR-mediated immune system genes indicated that B. plantarii ATCC 43733T has more diverse gene pairs in the QS-mediated AHL synthase-receptor circuit and in unique bacterial toxins such as tropolone and rhizotoxin.
We were a diverse lot: a pair of professors, a computer-game developer, a restaurant manager, a vacuum-cleaner repairman; black, white, Hispanic.
The value of the renminbi in relation to the dollar and other currencies influences, to a greater or lesser degree, the price of things as diverse as a pair of Gap jeans and an Apple iPod.
SMART brings together teams of students and faculty from diverse disciplines and pairs them with firms, organizations, or community groups located in developing countries.
