The phrase "altering can occur" is correct and usable in written English.
It can be used in contexts where changes or modifications are possible or expected to happen.
Example: "In this experiment, altering can occur due to variations in temperature and pressure."
Alternatives: "changes may happen" or "modifications can take place."
In addition to structural elements mentioned herein, missense mutations altering enzyme activity can occur at the heme-binding site, within the protein core, and at the protein interface involved in electron transfer from the redox partners, ferredoxin (FDX) and P450 oxidoreductase (POR) [ 11, 12].
If reward is held fixed, our model reduces to previous accounts [ 10, 36], but if reward is altered, parallel shifts can occur that violate the classical speed-accuracy trade-off, at least when signal-to-noise ratios are high and temporal discounting is small.
When the circadian rhythm is disrupted through sleep deprivation, global changes in gene expression can occur altering cellular behaviour.
Imaging luciferase reporter genes in intact animals enabled observations to be made in a physiologically relevant state without altered promoter control that can occur in vitro where cells are in artificial environments and are often dividing faster than in the animal.
These results reveal that alteration of the inner layers of the spore wall can occur without altering the permeability of the outer spore wall to protein-size molecules.
Estrogen alteration of cell function can occur by its well-described action in altering transcription and in turn protein levels.
More generally, replacements can occur without altering function, as exemplified by non-orthologous gene displacements (Trends Genet 12 334).
Microliter amounts of expensive chemokine solution are localized to the bottom compartment while flow substantive enough to deliver shear stress levels known to alter gene expression [13], [14] can occur on the apical side of the endothelium allowing for studies that otherwise may be cost prohibitive in macroscopic or even other microfluidic systems.
Once this balance is altered, an increase in intracellular ROS can occur.
Epigenetics – the idea that persistent changes can occur to genes without altering the actual sequence of DNA – has become not only a buzzword, but also an antidote to the genetic determinism of the early 21st century.
