Sentence examples for marking system that from inspiring English sources

The modifications of specific residues within the histone N-termini serve as a marking system that contributes to the establishment and maintenance of distinct chromatin structures [1], [2], [3], [4].

have emerged as key regulatory mechanisms of transcriptional regulation and may serve as an epigenetic marking system that is responsible for establishing and maintaining the heritable programs of gene expression during cellular differentiation and organism development [2] [4].

[ 1] These Histone modifications could act as marking system that is responsible for establishing and maintaining programs of gene expression during cellular differentiation.

The histone code hypothesis, originally proposed a decade ago [ 1], suggests that specific combinations of histone post-translational modifications (PTMs) constitute an epigenetic marking system that determines distinct transcriptional and functional outputs of eukaryotic genomes.

Our experiments used a simple, reliable marking system that does not involve GAL4, has zero-background and is inactive in postmitotic cells; we applied only a single brief heat shock.

While it has been reported that heat shock can alter ISC division rates measured by lineage labeling (Strand and Micchelli, 2011), we minimized these effects by using a single brief heat shock and a marking system that lacks GAL4.

Most of the claims that heat shock induces artifacts (e.g., Strand and Micchelli, 2011) are based on cell marking systems that involve the GAL4 system, which is itself affected by heat.

We have previously introduced image-guided biopsy marking system (IGBMS) that utilizes a computer-generated, electromagnetic tracking device to identify previously marked sites during upper endoscopy [ 6].

Beneath the actual (any one state of a system), we find "impersonal individuations" or intensive morphogenetic processes that produce system states and beneath these we find "pre-individual singularities" (that is, the key elements in virtual fields, marking system thresholds that structure the intensive morphogenetic processes).

One eagle-eyed player has the extra task of spotting a discrepancy in this complex marking system, in that there are two unattended opponents lumbering into the penalty area.

The MCQ uses a negative marking system such that candidates are awarded one mark for a correct answer, minus one mark for an incorrect answer and no marks if the question is not answered.
