The phrase "a complex network of molecules" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in discussions about biology, chemistry, or molecular biology.
Example: "The study focused on a complex network of molecules that interact to regulate cellular functions."
Alternatives: "an intricate system of molecules" or "a sophisticated arrangement of molecules".
Full expression of high-level methicillin resistance involves a complex network of molecules and depends primarily on sufficient expression of a penicillin-binding protein with low sensitivity towards BLAs.
The human body is a complex network of molecules, organelles, cells, tissues, and organs: an uncountable number of interactions and transformations interconnect all the system's components.
Co-culturing of human tumour cells and fibroblasts in 3D Matrigel in the absence of direct cell contacts stimulates the production of a complex network of molecules that induce invasion of both cell types generating a more aggressive phenotype.
In addition, as seen in both the ZIKV and DENV4 helicase structures, a complex network of water molecules is important for ssRNA binding, yet these water molecules may play different roles in recognizing an individual nucleotide.
Distant organs continuously communicate through a complex network of extracellular molecules.
When cells undergo DNA damage, a complex network of signalling molecules, the DNA damage response (DDR), is activated.
Elevation of the free cytosolic and nuclear Ca2+ concentration is an essential event during T cell activation and is controlled by a complex network of different molecules.
An affirmed realization from the post genomic era is that no gene functions in isolation, but rather is embedded in a complex network of interacting molecules [ 23].
Once the pathogen is detected, the plant relays a signal through a complex network of signalling molecules to transcription factors that activate transcription of defence proteins or production of secondary metabolites [ 2].
TGF-β/BMP signaling are finely tuned by a complex network of signaling molecules and biophysical factors, shedding light on some extremely relevant modulators namely FGF, HIF, GC, NO, PI3K, Akt, NF-κB, and mTOR.
The expression of these transcription factors is in turn controlled by a complex network of signaling molecules, including Smads, integrin-linked kinase (ILK), phosphatidylinositol 3-kinase (PI3K), mitogen-activated protein kinases (MAPKs), glycogen synthase kinase (GSK) 3β, and nuclear factor κB (NF-κB) (Zavadil & Bottinger, 2005; Thiery et al, 2009).
