Recent studies of RNA molecules that don't code for proteins show that those molecules have definite functions, even though they aren't conserved in the DNA codes of other mammals, said Job Dekker of the University of Massachusetts Medical School in Worcester.
A protein database search had shown that both tryptophans were not absolutely conserved in all identified viral p19 sequences, although all sequences conserved at least one of the tryptophans, with the other residue usually capable of forming a stacking interaction.
Prominent features of the M RNA segment are a high degree of divergence at the first part of the M genome, along with conservation of the middle and last regions and the 10-nt termini, which are conserved in all nairoviruses.
To accomplish this, Metropolitan will use water that has been conserved through an existing land management, crop rotation and water supply program with Palo Verde Irrigation District near Blythe, California.
These comparisons will promote understanding of molecular evolution, the significance of conserved sequences, the genetic basis of variable sensitivity to environmental agents, and the complex interactions between the environment and human health.
