  1. ...signatures about the protein structure-function relationships and provide an unbiased view of various protein functions in the context of human health. This information can be used to determine regional intolerance to variation, defined as the missense tolerance ratio (MTR), which is an indicator...
  2. ...sex-ratio). Our results do not support such an effect because no significant difference in recombination rate was observed between autosomes and the Z Chromosomes.A clearly deviating recombination rate was found for Chromosome 16 (15.3 cM/Mb), and that explains why the association between chromosome...
  3. ...bovidae ancestral chromosomes (Table 1; Supplemental Table S3).Evolutionary breakpoint regions and multispecies homologous synteny blocksWe identified and classified genomic intervals that flank EBRs as well as mammalian msHSBs found in the cattle . Pairwise HSBs were defined at 300-kbp resolution...
  4. ...the goodness-of-fit of statistical phylogenetic models. Specifically, we can perform a likelihood ratio test (LRT) to assess precisely whether a small estimate of ls explains an observed alignment window better than the average rates assumed by the Figure 1. (A) Examples of local synonymous rate variation...
  5. ...ratio and d N / d S rate ( Yang and Bielawski 2000 ; Nekrutenko et al. 2002 ), but it is more suitable for -wide gene identification strategies with many informant s. In contrast to methodologies that focus primarily on high sequence conservation to identify candidate genes, the RFC and CSF metrics...
  6. ...reference virus had a viral Ct higher than 25). To evaluate the relative sensitivity of enrichment, reference virus NAs were first serially diluted (1:10), then mixed with a constant amount of A549 RNA (samples were prepared using a 1:1 ratio by volume). NAs extracted from clinical specimens were either...
  7. ...(corresponding to an average sequence identity of 0.705), and we used a geometric indel model with substitution/indel rate ratio of γ = 7.5 (see Methods section). These parameters result in sequences that are comparable to sequence at human–mouse divergence (mean sequence identity 69%). The simulated sequences...
  8. ...of corresponding genomic regions. The regions that are translated in alternative frames are expected to evolve under purifying selection with the ratio of nonsynonymous to synonymous substitutions being significantly below 1 for the amino acid sequences encoded in alternative frames. Also the regions of dual...
  9. ...,000 regions of length 1 Mb. Ascertainment correction was made using the two-dimensional frequency spectrum (for both populations together), by retaining variable sites from the simulated data with a probability equal to the ratio of the per-base-pair frequencies of the 2D frequency class between the Hap...
  10. ...acid level for the reconstruction of the ancestral CFTR protein. This corresponds to an ∼99.5% accuracy at the base level, because roughly 2/3 of random base changes are nonsynonymous, and there is a 3:1 ratio of bases to amino acids. This is not as good as the 99.8% accuracy expected, based...
