A variety of strategies involving high-throughput DNA sequencing or hybridisation to oligonucleotide micorarray may be used for the genome-wide analysis of DNA methylation pattern (reviewed by Zilberman and Henikoff, 2007).
Many physiological functions of the retina such as visual sensitivity or the shedding of photoreceptor outer segments show a circadian pattern (reviewed in Guido et al. [2010]), strongly arguing for the existence of an autonomous oscillator in the retina (reviewed in Green and Besharse [2004] and Tosini et al. [2008]).
Under Holder's tenure, the department has launched 20 "pattern and practice" reviews of police departments — twice as many as under his predecessor — and prosecuted more than 300 individual officers for misconduct, he said.
A full comparison of the two perspectives exceeds the scope of this paper, and is complicated by the fact that the authors inherently focus on processes generating variation rather than variational patterns reviewed here, but some will make the point.
Embryological and genetic analysis has demonstrated that the AVE is required for anterior patterning (reviewed in [7], [8], [9]).
The relatively few studies that have documented intraspecific allometric variation have shown departures from the universal patterns (reviewed by [6]).
The development of the retina in the Drosophila compound eye has long been a model system to study how extra-cellular signaling generates precise cellular differentiation patterns (reviewed by reference [1]).
In vertebrates, hemichordates, and echinoderms, Wnt signaling is essential for posterior patterning (reviewed in [ 58]).
Phases included familiarisation with the data; generation of initial codes; searching for themes or patterns; themes and patterns reviewed; and, themes and patterns defined and named.
Gene deserts enriched for HCNRs is a genomic feature characteristic of developmental genes with tightly regulated expression patterns (reviewed in Alonso et al. 2008).
