Sentence examples for the pattern of presence from inspiring English sources

"The pattern of presence and absence of the anus in animals is quite fascinating," says Dr Hejnol.

The assumption behind the use of this approach is that, if the pattern of presence and absence of two or more proteins in a number of genomes is very close, this is an indication of co-evolution among the proteins.

We devised a naïve Bayesian network that based on the pattern of presence and absence of motifs in 5' UTRs and 3' UTRs can predict whether a gene belongs to a particular pathway (see Methods section).

The pattern of presence and absence has been explained both by horizontal gene transfer (HGT) and co-maintenance and long term co-maintenance followed by lineage sorting (some lineages losing eEF1A and some losing EFL) [ 12- 17].

The pattern of presence or absence of a gene can also be a strong indicator of LGT, especially for genes found only among members of distantly related lineages, though the impact of gene loss cannot be discounted (Zmasek and Godzik 2011; Wolf and Koonin 2013).

With data on multiple crosses, the simplest approach to identifying the location on the tree at which a QTL arose is to compare the pattern of presence and absence of the QTL in the individual crosses and match that to the ideal (see the table in Figure 1).

This provides high confidence in the patterns of presence and absence that we have determined for these sRNAs.

The similarity of the genomes in terms of genomic content was calculated from the patterns of presence and absence of non-core regions.

A recent comparative genomics study [ 9] has provided a comprehensive view of the patterns of presence and absence of OXPHOS components in 27 fungal species.

By phylogenetic timing, we mean the inference of relative evolutionary timing of gene duplications on the basis of the patterns of presence or absence of orthologs and paralogs in genomes of extant species, assuming a known and trusted species tree.

Second, due to the lack of an appropriate outgroup (e.g., an additional Spiroplasma species in the Citri clade), we cannot establish the directionality of evolutionary changes based on the patterns of presence and absence.
