The phrase "a more complex regulation" is correct and usable in written English.
You can use it when discussing rules or laws that have multiple components or are difficult to understand.
Example: "The new policy introduces a more complex regulation that requires businesses to comply with additional environmental standards."
Alternatives: "a more intricate rule" or "a more detailed regulation".
The increase of genomic complexity is thus associated with a more complex regulation of gene expression since the additional genetic information has to be integrated into the existing regulatory network basically operating in a bacterial cell.
In three instances, a more complex regulation may exist, where an additional sensor or response regulator gene is adjacent to the pair, namely AB0416, AB0417, AB0418; AB0454, AB0455, and455; AB07950795, AB0796, AB0797.
miR* accumulation may also be developmentally regulated in the silkworm, which suggests a more complex regulation of miR and miR* sequences than was previously proposed.
It is also possible that these miRNAs and targets are regulated by other unidentified factors associated with a more complex regulation [ 52, 53].
Thus, the proportion of TFs in larger genomes would be consistent with the hypothesis that an increase of genome complexity and physiological functionality is generally associated with a more complex regulation of gene expression since the additional genetic information has to be integrated into the existing regulatory networks that operate in a bacterial cell [ 25].
These data are consistent with a previous observation that an increase of genomic complexity and physiological functionality is generally associated with a more complex regulation of gene expression since the additional genetic information has to be integrated into the existing regulatory networks that operate in a bacterial cell [ 17].
Given that both mouse and ferret form cortical areas, but only ferret forms folds, this again supports a role for genetic modularity in cortical folding, or a much more complex regulation of cortical area patterning than in mouse (Sansom & Livesey, 2009; Elsen et al, 2013).
One explanation for our findings may be a far more complex regulation of CDA gene transcription, leading to substantial interindividual differences in quantities of CDA enzyme, unrelated to the 79A > C polymorphism.
These findings suggest that it is not merely an immediate transcriptional response by HIF, but rather an indirect and more complex regulation.
The diversity of Arc methylation patterns may be a result of the more complex regulation of the Arc gene, since its expression is strongly induced by neural activity, whereas the Gabra5 gene remains primarily constitutively expressed.
If sufficiently elucidated, cis-regulation at the promoter will become a powerful design parameter for more complex regulation.
