The answer is partly that flies and worms have lots of genes that do specific things for them.
"Why they need to be so conserved remains a mystery," he said, noting that even regular genes that do something undergo more change over time.
But, in the end, it is proteins, not genes, that do the actual work in a cell.
Both plants and animals, probably independently, evolved genes that do not make proteins but simply generate an RNA molecule that loops back on itself to form a hairpin twist similar to a virus's double-stranded RNA.
Thus there are major resistance genes that do not seem to be affected by nitrogen supply.
In Bombyx mori, 12 BESS-DC genes that do not contain intron in the BESS domain region were localized to eight chromosomes.
The crossover technique adopted in our approach is the conflict-based crossover; this method distinguishes between genes that do not create a conflict from genes creating conflicts.
In this paper, we propose a new method for the prediction of protein coding regions that is designed to detect novel genes that do not have known, close homologs.
According to Matthew Hill, an associate professor of neuroscience at the University of Calgary in Canada, candidate genes that do both have already been identified.
Interestingly, genes that do not undergo AS were significantly enriched within single-promoter genes.
Presumably, genes that do not have a strong Met4 site, but have the expected microarray data are indirectly regulated.
