The Hydrophobic Effect Has the Greatest Influence on Protein Stability. The hydrophobic effect, which causes nonpolar substances to minimize their contacts with water, is the major determinant of native protein structure.

The band-sharpening effect relies on the fact that negatively charged glycinate ions (in the electrophoresis buffer) have a lower electrophoretic mobility than do the protein–SDS complexes, which, in turn, have lower mobility than the chloride ions (Cl − ) of the loading buffer and the stacking gel buffer. 

[Cl−] > [protein–SDS] > [glycinate].

Microbial leaching of copper with the common copper ore CuS, in which copper exists as Cu2+   Acidophillus ferrooxidans oxidizes the sulfide in CuS to SO42, releasing Cu2+.

Individual nucleosomes can be obtained by treating chromatin with the endonuclease micrococcal nuclease (MNase), which cuts the DNA between nucleosomes, a region known as linker DNA.
