DNA methylation is one of a group of epigenetic modifications to the genome which affect the ability of specific genes to be expressed but do not modify the sequence of the genome itself.
A second group of modifications concerns the relational associations between tags and questions, and between related questions to facilitate the user's navigation interface to explore questions.
This new lead compound is among the most active from a group of related structural modifications.
10 The epigenome is defined as the group of modifications that can occur at a genomic level that will not change the sequence of the bases of the DNA but can change the DNA conformation and, as a consequence, change the expression of genes.
PcG and TxG proteins constitute a group of critical regulators of epigenetic modifications affecting differentiation during development.
In support, smooth colonies up-regulate the expression of a group of genes involved in histone modification and chromatin remodeling (Table 1).
Polyethyleneimine-based polymers represent a group of chemical compounds for the modification of metal nanoparticles (NPs), which provide good biocompatibility to the resulting nanocomposites.
An initial group of modifications was made to cope with the epidemiological specificity of EpiBasket: the catalogue's offered 'e-commerce products' are 'epidemiological questions'.
Among the down-regulated genes, similar gene categories could be recognized, although no genes related to ethylene response and carbohydrate metabolism and glycolysis were present, while a group of genes related to 'cell wall' modification could now be identified.
Fortunately, the nature of search engine applications allows us to concentrate on improving the throughput of large groups of modifications, not the latency of individual updates.
The resulting dendrogram on the top of Figure 3 unravels three distinct groups of modifications with histone acetylation separating from the rest, which further divides into histone phosphorylation and histone/DNA methylation.
