Sentence examples for constrained elements of from inspiring English sources

Ultraconserved elements (UCEs) are highly constrained elements of mammalian genomes, whose functional role has not been completely elucidated yet.

We assessed the effectiveness of our SVM-based approach to detect selective constraint by performing forward simulations of functional 10 kb windows containing constrained elements of various sizes, and experiencing varying strengths of negative selection, as well as nonfunctional 10 kb windows evolving entirely under drift.

A main disadvantage of the window-based approach is that it uses a fixed window size, while in reality the constrained elements may be of different sizes.

Ensembl provides a nucleotide level GERP (Genomic Evolutionary Rate Profiling) scoring [43], that reflects the amount of inferred substitution, which in turn allows the identification of constrained elements.

Similarly, a comparative analysis of 29 mammalian genomes revealed that the majority of evolutionarily constrained elements occurred in intronic (29.7%) and intergenic (38.6%) regions that were not associated with known protein-coding transcripts (Lin et al. 2011; Lindblad-Toh et al. 2011).

This suggests that at least a fraction of these constrained elements might not be functionally important.

Overall, we obtained 31 292 constrained elements, covering a total number of 1.8M bp.

Our annotation resolved cat homologues of 743,362 evolutionarily constrained elements (ECEs) recently identified in the human genome by alignment to 29 different mammalian genomes [ 10] and these were compared to the conserved sequence blocks obtained by the reciprocal best match (RBM) screen for cat genes with seven mammalian genomes (human, chimp, macaque, dog, cow, rat and mouse).

Of the ~1.1 million constrained elements that arose during the 90 million years between the divergence from marsupials and the eutherian radiation, we can trace >19% to mobile element exaptations".

Constrained elements result from GERP-scoring[ 26] of each base pair position within a multi-species alignment.

We do not identify overlap between any of the SNPs and evolutionary constrained elements.
