The phrase "actively marked" is correct and usable in written English.
It can be used in contexts where something is clearly indicated or highlighted, often in discussions about language, grammar, or data.
Example: "In the text, the important terms were actively marked to draw the reader's attention."
Alternatives: "clearly indicated" or "explicitly highlighted".
Thus, rather than poising for activation or prolonged inactivation, as was proposed for the bivalent genes, Ring1b might be required to modulate the transcriptional activity of this subset of actively marked genes in ES cells and during later developmental stages.
Two actively marked toxic strains of Bacillus sphaericus (Fathy, 2002), previously isolated from the soil of north Sinai in Egypt, identified morphologically, biochemically and assayed biologically against mosquito larvae (strains are available in Culture collection of Cairo "MIRCIN" under numbers EMCC 1931 and EMCC 1932, Agric. Faculty, Ain Shams University).
We suggest that Ring1b contributes to stable maintenance of pluripotency of ES cells by repressing bivalently or actively marked genes.
Moreover, a large subset of actively marked genes retain this mark and corresponding transcriptional state in more committed NPCs and MEFs [30].
Unexpectedly, Ring1b binding did not correlate with low expression levels of H3K4me3 marked genes, but instead seemed to associate with these actively marked genes indifferent of their level of expression (Figure 6G).
It is also during this time window that gene silencing initiates on the X-chromosome, with genes shifting from outside to inside the Xist RNA compartment, which is depleted for actively marked chromatin and enriched for inactive chromatin, as they become silenced.
I myself assisted in founding the European Girls Mathematical Olympiadd, which is now in its fourth year, and actively mark the corresponding UK selection paper.
This comparative analysis also revealed that a considerable number of actively transcribed H3K4me3 marked Ring1b bound genes are regulated (mainly repressed) in ES cells.
During the recovery period, the microspheres are actively engulfed by phagocytically active plasmatocytes, marking these plasmatocytes during subsequent analysis.
The promoter proximal peaks common between K562 and GM12878 are enriched for Pol2, the active marks H3K9Ac and H3K27ac, and the transcription elongation mark H3K79me2; this evidence suggests that these regions are actively transcribed promoters.
Red hotspots mark actively burning fires.
