The phrase "a detectable role" is correct and usable in written English.
It can be used when discussing the presence or influence of something that can be observed or measured in a particular context.
Example: "The study aimed to identify a detectable role of environmental factors in the development of the disease."
Alternatives: "an observable role" or "a measurable role".
But carbon dioxide has only a very minor, hardly detectable role.
In a previous study, Faith and Polleck also concluded that transcription plays no detectable role in producing the gradients of asymmetry at redundant sites by separately analysing the four-fold redundant sites in nad6, the only gene transcribed on the minority strand in vertebrate mitochondrial genome [25].
Additionally, HSF has no detectable role in the rapid HS-repression of thousands of genes.
We show here that such cleavage plays no detectable role for chromosomal events of prophase.
We show below that matrix resorption and remodeling play no detectable role in shape development, at least during early stages.
These experiments demonstrate that NOX1 is an important protein involved in migration and tube-like structure formation of endothelial cells with no detectable role in cell proliferation.
Tests of plant traits indicated that the crayfish responded primarily to plant structure, the apple snails primarily to plant chemistry, and that plant protein concentration played no detectable role.
RabX1 and RabX2, two members of the trypanosome Rab subfamily, were shown to have no major detectable role in intracellular transport, despite the localization of each gene product to highly specific endomembrane compartments.
Taken together, our data indicate that the CDC27 ubiquitin ligase is essential for F. tularensis to evade lysosomal fusion, while the USP22 ubiquitin-specific peptidase and the PI4KCA PI4 kinase are only required for bacterial proliferation in the cytosol, but play no detectable role in evasion of lysosomal fusion.
We determined that variations in sap flow also played no detectable role in the magnitude or polarity of the sustained voltage since we mechanically stopped all flow in one experiment by inserting razor blades above and below the length of the electrode and by using severed branches in other experiments.
