Furthermore, for the same strength of weak constraint, the measurement of conservation will typically vary with branch length and depend on the orientation of selection, that is, which particular bases are the preferred states in relation to the mutational biases.
The multi-orientation EPIs and optimal orientation selection are proved to be effective in detecting and excluding occlusions.
This integration pattern provides evidence for selection against CfERVs in sense orientation relative to chromosomal genes.
The recommended standard settings were used for selection of 35- to 45-nt oligomers in the sense orientation, with the melting temperature of target:probe hybrids varying from 70°C to 75°C.
Importantly there is substantial overlap between all four selection criteria (stage, orientation, immunophenotype, and genotype), suggesting these criteria can be used in concert to provide corroborating evidence for selection.
However, to determine whether the observed IS orientation biases could just reflect a general preference for insertion in a specific orientation or the effect of selection, we determined global orientation for non-IS encoded and IS-encoded genes in 1,727 bacterial chromosomes (fig. 2).
First and second strand cDNA synthesis, RsaI endonuclease enzyme digestion, adapter ligation, hybridization, and PCR amplification were performed as described in the PCR-select cDNA subtraction kit manual (Clontech, Palo Alto, CA, USA) with modifications as described in [ 55] for the Mirror Orientation Selection protocol.
He's available for selection.
Everybody was available for selection.
