Cdc2/Cdc13*, the highly activated form of the complex Cdc2/Cdc13, has to be actively maintained by a positive regulatory signal, therefore θi = 1 for this node.
However, the interstitium is actively maintained by the relationships between itself, myocytes, the neurohormonal system, mechanical forces and cardiac fibroblasts [13].
The biological interest is focused on the species-rich mesotrophic grassland found across the site, which is actively maintained by grazing.
This is in keeping with the proposed model of cis-regulated alternative splicing we have developed, where alternative splicing is actively maintained by balancing selection (see below).
Taken together, these data indicate that divergent bacterial genomic GC content has evolved repeatedly and is actively maintained by contemporary bacterial species.
An additional idea is that stability is actively maintained by ATP-dependent chromatin remodelling enzymes, an idea supported by the strong effects on nuclear-wide chromatin condensation caused by blocking ATP synthesis [44].
Interestingly, our simulation of mutations produces the seemingly opposing result that timing robustness is not itself robust to mutations – from which we conclude that it is a property that must be actively maintained by evolution.
By contrast, H3K36me3 is actively maintained by MES-4 in these cells.
The database will be actively maintained by members of the bioinformatics core, cancer vaccine center, the Dana-Farber Cancer Institute.
Stingless bee trails must be actively maintained by bees interrupting their food collection, and begin to fade out after approximately 20 min without such maintenance.
