Residues which bind the RBE display nearly perfect conservation except for two conservative substitutions near aa 140.
β-actin is highly conserved across all metazoan taxa, and given the perfect conservation between human, mouse and chicken we did not sequence it for analysis in our rodent species.
The reason for this perfect conservation might be that this short sequence is targeting a conserved sequence element in one or several other RNAs, mRNAs or ncRNAs, through base-pairing interactions as it is known for many ncRNAs.
A higher-order divergence-free interpolation for convective velocities is developed which ensures a perfect conservation of mass and momentum on momentum control volumes.
This indicates that the assumption of perfect conservation is not accurate.
In short-read assemblies almost all nucleotides had perfect conservation, with some outliers corresponding to heterozygous SNPs (around 50%).
This close approach of the two backbones is reflected in the perfect conservation of this glycine in the KITGMLLE motif.
This revealed perfect conservation of the splice donor with only one occurrence of an atypical GA splice site (Dasypus novemcinctus).
Ultraconserved elements were first defined as sequences at least 200 bp long that show perfect conservation in alignments of the human, mouse and rat reference genomes (perfect HMR conservation).
To build an expected length distribution of segments with perfect conservation, we assumed that the identity of each base was independent of all other bases and randomly swapped the columns in alignments of non-coding portions of the three genomes.
In this paper, our search for novel miRNAs is based upon the perfect conservation of sequence among two sets each comprised of three species in relation to rare tissue progenitor sequences.
