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).

Answer:
here
Explanation:
There will be the nitrogenous bases (adenosine, cytosine, guanine, thymine), held in complementary pairs (A T, C G) by hydrogen bonds. Weak van der Waal's forces exists between the 'rungs'.
In terms of the scientific method, the purpose of an experiment is to:
D) Test a hypothesis
After forming a hypothesis, you TEST it out by performing the experiment and collecting data. After collecting the data from the experiment, you can form a conclusion about the results of the experiment.
An experiment is supposed to tell you whether the hypothesis you came up with is true and is able to be proven with an experiment.
The purpose of an experiment is to test a hypothesis and see whether the results you get support or contradict your hypothesis.
