Sentence examples for marks at both from inspiring English sources
The larval stages also show a pattern of reciprocity for the two silencing marks at both euchromatin gene promoters as well as the repetitive elements.
Additionally, depending on which parent contributes the null mutation of the HP1a gene, the levels of the H3K27me3 and H3K9me3 silencing marks at both promoters and heterochromatin are different.
This recruitment of UTX coincides with a loss of the antagonistic Ezh2 H3K27 methyltransferase enzyme and removal of the repressive H3K27me3 mark at both genes.
Sew your 3 layers together with a 1/2 inch (1.3 cm) seam allowance around the perimeter, but inside the 4 inch (10.2 cm) fringe mark at both ends.
Luciferase expression from these sites is regulated by the HSI2 PHD-like domain, which is required for the deposition of repressive histone methylation marks (H3K27me3) at both Kan R and Kan S loci.
We found that genes that were susceptible to KRAB/KAP1-mediated silencing carried higher levels of repressive histone marks both at the promoter and over the transcribed region than genes that were insensitive.
Interestingly, we also detected a massive spreading of both marks at least 5 kb upstream and 15 kb downstream from the zinc finger-binding site.
Constitutively, the epigenetic balance is shifted toward higher levels of permissive epigenetic marks at angiogenic loci in both endothelial cells and pericytes by the activity of cell type-specific and general transcription factors.
It is also important to mention that the combinatorial patterns of bivalency might simply reflect allelic differences in chromatin modifications, explaining the apparent coexistence of both histone marks at the same loci, as shown in Figure 3C.
There is therefore marked redundancy at both the intra- and inter-domain levels in the molecular determinants that govern oligomerization of TPCs.
Recent analyses of the diversity of yam revealed marked variability at both morphological [ 12, 13] and at molecular level [ 14] but also showed that yam genetic diversity is highly structured [ 15].
