Small bone fractures that develop in response to repetitive, cumulative trauma are known as stress fractures. These are fractures where bones are injured by overuse, they are commonly found in the spine, vertebrae, leg bones, feet, and the pelvis. They result from the accumulated trauma from repeated submaximal loading, such as running or jumping
DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.
<h3>What is centrifugation?</h3>
Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.
It is the frequently applied techniques in the molecular biology laboratory.
The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.
Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.
