The phrase "alterations are based on" is correct and usable in written English.
It can be used when discussing changes or modifications that depend on certain criteria or factors.
Example: "The alterations are based on the feedback received from the initial review."
Alternatives: "modifications are determined by" or "changes rely on".
These alterations are based on variations in molecular weights and intensities of polypeptides bands as well as gain or loss of protein bands that led to highly levels of protein polymorphism.
These protein alterations are based on changes in bands molecular weights (MWs), bands intensities, fractionation of some bands, appearance of new bands (unique bands), and disappearance of some bands (polymorphic bands) as shown in (Table 3) and.
These alterations are based on variations in number of polypeptide bands, molecular weights, and intensities of polypeptides bands as well as gain or loss of protein bands that led to high levels of protein polymorphisms.
