Answer:
Silent mutations do not affect protein function
Explanation:
A mutation is defined as any alteration in the genetic material of a cell of a living organism. Moreover, a silent mutation refers to any mutation that does not alter the phenotype of the cell/organism (they are evolutionary neutral mutations). Silent mutations are base substitutions that do not alter the amino acid sequence of the resulting protein, and therefore these mutations do not alter protein function.

Extraction, homogenization, and centrifugation are the three processes in cell fractionation.
Cell fractionation is a method for dividing cellular components while yet maintaining each component's unique functionality. This technique was initially applied to show where distinct biochemical activities are located within cells. Subcellular fractionation is also used to help with illness detection and to offer an enhanced source of protein for further purification. To prevent osmotic damage, tissue is routinely homogenized in an isotonic buffer solution. Grinding, mincing, chopping, pressure changes, osmotic shock, freeze-thawing, and ultrasonic waves are a few of the mechanisms for homogenization. After that, the samples are maintained cool to avoid enzymatic deterioration. It is the development of a uniform mass of cells (cell homogenate or cell suspension).
