The phrase "a repeating backbone of" is correct and usable in written English.
It can be used to describe a fundamental or essential element that recurs throughout a particular context or structure.
Example: "The project was built on a repeating backbone of collaboration and innovation, ensuring that every team member contributed their unique skills."
Alternatives: "a consistent foundation of" or "a recurring core of".
However, a repeating backbone charge dominates the biophysics of a DNA polymer so much that one can change its sequence without changing its biophysical properties.
After the formation of the repeating disaccharide backbone of HS chains by EXTs and EXTLs, GlcNAc residues are converted into GlcN residues by GlcNAc N-deacetylase [ 6, 14, 198].
Dextran is a branched polysaccharide made up of glucose molecules with a linear backbone of repeating units of α-linked D-glucopyranosyl.
Polyphosphazenes are comprised of an inorganic backbone of repeating phosphorus and nitrogen atoms with alternating single and double bonds [ 6, 17– 17].
Based on these observations, we identified and integrated all the 100% identical repeats of at least 300 bp in the NCBI version 36.2 human genome reference assembly into non-overlapping regions, thus defining the Identical Repeated Backbone (IRB) of the reference human genome.
Synchrotron X-ray reflectivity (XRR) shows significant differences between the ordering in thin films of diphenyl-based siloxane oligomers with single versus double backbones of –Si O– repeating groups.
The proposed structure of Pazur's diheteroglycan is a backbone consisting of a trisaccharide repeating unit of →4 -β-Glc-(1→4 -β-Glc-(1→4 -β-Glc-(1→6 -β-Glc-ted with lactosyl and cellobiosyl side chains attached by β-(1→6 -β-Glc-es to alternate glucose residues of the backbone [5].
Interestingly, the only established glycoprotein glycoslytransferases capable of transferring GlcA in a β4-linkage are the dual-activity exostoses enzymes involved in heparan sulfate (HS) proteoglycan polymerization that build the repeating disaccharide (-GlcNAc-α4-GlcA-β4) backbone of the glycosaminoglycan (Zak et al., 2002).
By then, through a new burst of model building, I had found that a sugar-phosphate backbone of 20-angstrom diameter optimally repeats every 34 angstroms, the repeat distance measured in B-form DNA.
Such polyimides had better solubility than those containing only one isopropylidene unit or a hexafluoroisopropylidene linkage in the repeating unit of polyimide backbone.
