Considering the tremendous diversity of epigenetic marks, which include dozens of different post-translational histone modifications and more than 50 million sites of potential DNA methylation in a diploid human genome (and thus >250M possible epigenotypes!), it seems that no two human cells would have identical epigenomes.
Thereby, the amount of methyl tags on the same lysine residue may function as repressive or activating signs in S. cerevisiae, while the fission, filamentous, and higher multicellular systems use additional signs carried by a larger number and diversity of methylation marks.
It's your cosmopolitan embrace of diversity that marks you as a sophisticated and learned 21st-century person, and that distinguishes you from all the philistines wedded to their chauvinistically narrow sets of cultural preferences.
Given the lack of diversity that marked earlier generations of Canadian governments, in which a token "Italian" would seem generous, getting fussy about quotas can appear petty.
The diversity of DNA that marks the telomeric/subtelomeric regions facilitates the task of sequencing regions at the chromosomal ends.
For example, a typical high school textbook might use a phylogeny to illustrate the diversity of animal life, marking the evolution of key traits such as radial symmetry or the coelom.
Recent analyses of the diversity of yam revealed marked variability at both morphological [ 12, 13] and at molecular level [ 14] but also showed that yam genetic diversity is highly structured [ 15].
There was marked diversity of miRNA expression resulting in a clear separation of these three different lineages.
It may turn out that the rise of diversity marked the end of the golden age of affirmative action.
In the transition phase, inequality between subpopulation becomes minimum as effect of interactions between A and B. Therefore, attainment of maximum diversity may mark the beginning of an ideological shift.
Willis stated that the major challenge when creating the brand identity for Beckham was: "How do you convey through a brand mark the sheer diversity of the David Beckham world?".
