DNA methylation is a heritable epigenetic mark, enabling stable but reversible gene repression.
The marking enables a set of transitions (tau subseteq T).
This model is similar to proposed inheritance models for histone marks where the histone methyltransferases remain associated with the chromatin domains containing their own mark enabling faithful maintenance [ 21, 26, 27].
This so-called bivalent mark enables pluripotent cells to respond rapidly to differentiation signals, and ESCs that lack critical PRC1 or PRC2 components display global derepression of these target genes (Azuara et al., 2006; Boyer et al., 2006).
This, together with domain rather than individual skill marking, enables the assessment of communication skills across a wide variety of consultations, especially helpful in real-world consultations where communication checklists cannot be specific and tailored for each case.
In addition, if the mouse was disturbed, perhaps by a predator alarm, the way-mark enabled it to orient quickly back to the place where it had previously had a temporary focus of interest (for example for digging or collecting bedding)).
Masoretic text, (from Hebrew masoreth, "tradition"), traditional Hebrew text of the Jewish Bible, meticulously assembled and codified, and supplied with diacritical marks to enable correct pronunciation.
Fired cartridge cases and bullets bear characteristic marks, which enable firearm examiners to identify the firearm that fired them (Kinder et al., 2004).
During differentiation, these regions can be resolved into either active H3K4me3 or inactive H3K27me3 marks and enable rapid activation or silencing of the underlying genes [33,34].
25 It should also be noted that decreasing the length of the recall interval will result in increased sample size requirements that may be logistically unfeasible, but evaluators should at the very least collect data on diarrhea onset at the 1- and 2-week marks to enable estimation of the level of recall decay present in the data.
