The phrase "basis of this difference" is correct and usable in written English.
It can be used when discussing the underlying reasons or foundations for a particular difference or distinction.
Example: "The basis of this difference lies in the varying cultural perspectives on the issue."
Alternatives: "foundation of this difference" or "reason for this difference."
On the basis of this difference, different zones for determination of transformation parameters have been proposed.
The physiological basis of this difference is examined here in a comparative study of two ecotypes that differ in tolerance and maximum growth rate, using a growth analytical approach.
On the basis of this difference, we hypothesized that, in a mixed system, 1 should assemble at a higher pH than 2 (Fig. 1b).
To explore the molecular basis of this difference between Sto-GAPN and Sso-GAPN, we generated 14 mutants and 2 chimeras.
Once a specific isotope has absorbed radiation and has reached an excited state, its properties may become quite different from the other isotopes; it is then separated on the basis of this difference.
To pin down the genetic basis of this difference, the researchers then mated the offspring of hybrid mice and measured the midpiece length of their descendants and the speediness of their sperm.
As part of the investigation to establish the basis for this difference, samples of "Miltefos" were sent to the Academic Medical Center, University of Amsterdam and to the London School of Hygiene and Tropical Medicine (by WHO).
It is unlikely that regulation of expression is the basis for this difference since available transcription data in the Serial Pattern of Expression Levels Locator (SPELL; spell2.princeton.edu/) database show a high degree of coregulation of homologous pairs of ribosomal genes for cells in exponential and stationary phases as well as during heat shock.
It has also been observed that long-term outcome in AS is worse in men than in women [ 14, 15], but the basis for this difference in severity of clinical expression remains unclear.
We discuss what is known about the genetic basis of this species difference derived from classic quantitative genetics and quantitative trait locus mapping experiments.
The molecular basis of this phenotypic difference was demonstrated by showing TG-resistant cells had lower levels of HPRT mRNA than cells treated with Dox (Fig. 3) and molecular changes associated with epigenetic silencing (Figs. 4, 5, and S2).
