(The phenomenon has been called "gene shifting").
A copy of a key lung gene shifted where it is active, rendering skin capable of efficient gas exchange, they reported here this week at the annual meeting of the Society for Integrative and Comparative Biology.
The 'proof of principle' of gene shifting has already been established (22– 22).
Several DNA repeat oligonucleotides were inserted after the translation initiation codon of the EGFP gene shifting it out of its reading frame and resulting in the expression of a truncated peptide without fluorescence.
To understand the discontinuity, we checked the sensitivity of genome elements falling into the attractor, i.e., changing from 0 to 1 or vice-versa for single-gene shift (Figure 4A, right panel).
This expansion of a genome element shows fractal-like binary distributions and the sensitivity of single-gene shift within a genome element demonstrates the non-linear nature of gene expression dynamics.
Furthermore, transitions in rank position should determine which genes shift in expression concurrent with the new dominance status.
The emerging picture is that functional groups of genes shift their gene expression patterns during carcinogenesis in association with specific combinations of epigenetic modifications.

These results indicate that both in eudicots and monocots, the major products of MIR159 or MIR319 genes shift to ACR miRNAs in a highly spatio-temporal specific manner during plant development.
They checked the offspring's DNA to see how the frequency of different versions of their genes shifted compared with those frequencies in the parents.
