The agglutinate component has proven difficult to replicate, yet it typically constitutes 25 30%, and up to 60%, by volume of the lunar soil.
Although these results are promising they are not replicated yet.
This replicated, yet independent evolutionary history facilitates the identification of traits that may have evolved in parallel and are possible instrumental candidates for adaptation to a marine habitat.
We cannot exclude the possibility that in a small subset of cells RNA polymerase II occasionally does engage the a1 promoter at HMR, perhaps when the chromatin is replicated, yet fails to elongate all the way through silenced chromatin.
Graf et al. [ 12] reported an 80% prevalence of mental disorders in a study of 103 children and adolescents in German group homes, but this study was based only on a general clinical judgment without specifying diagnostic criteria and has not been replicated yet.
Biological systems replicate, yet Koonin tells us we can not know how they happen to do it in the first place and that we need to seek for an answer outside of the realm of traditional evolutionary thinking to address this question.
Proteins have no nucleic acids and so no means of reproducing or replicating -- yet Prusiner was proposing that they could spread like an infection, taking over healthy proteins and making them lethal to the parent organism.
And as the visual web matured, this problem seemed to be replicating itself yet again.
Outliers are data points that are not faithfully reproducible among replicates, yet have a disproportionately large effect on the average values.
However unlike genes in Cluster 1, these genes displayed a high degree of heterogeneity in expression levels between replicates, yet still remained highly correlated.
The absolute level of expression of these genes varied greatly between technical replicates, yet the correlation of expression profiles within the cluster remained high.
