Therefore, increased rates of non-synonymous substitutions at the ABS contact residues are not the only mechanisms that result in variable sequences or/and more alleles.
Libraries prepared in different ways have been shown to result in variable sequencing efficiencies for individual miRNAs, so that differences in miRNA read counts between libraries may be caused by differential cloning efficiencies rather than reflect differences in their expression.
Afterwards it actively calls sows to the feeder in a variable sequence in order to minimize queuing and thereby reducing aggression, stress and injuries associated with feeding.
Nine white squares are presented on the screen, some of which momentarily change in color in a variable sequence.
White squares are shown, some of which briefly change color in a variable sequence.
Unfortunately, accurately evaluating growth velocity is fraught with difficulty since comparing two measurements compounds the effects of measurement error, and since head growth occurs in a variable sequence of relatively slow and fast periods [ 21- 24].
In addition, 3 genes could have their expression modified by a deletion/insertion in a phase variable sequence in their promoter region.
Different patterns in the most variable sequence were attributed to variations in complex microsatellite repeats.
Considering the above genomic differences, we analysed in more details the possible phenotypic consequences of (i) the loss of lgtB, (ii) the change in the phase variable sequence of the hemoglobin binding proteins and (iii) the heterogeneity in pilin sequences.
The variable regions are all linked to translocation breakpoint flanking sequences, thus, it is possible the information lies in these flanking sequences, or in the variable sequences themselves with perhaps a mechanism analogous to microsatellite replication [ 34].
Although it is clear that the N-terminal is the most variable sequence in this protein family, the role of their hydrophobic segment in not fully understood.
