Through centrifugation it is crammed down at the bottom of the spin tube.
Gel electrophoresis
Mitosis
The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA. It is separated from the rest of the cell by a double layer of membrane. The mitochondria also contain DNA, called the mitochondrial DNA.
First off, an English correction. You can't contain a lack of something, as there is nothing to contain. What I think you mean to ask is Do the prokaryotes lack a nucleus?If this is the question then the answer is yes, the prokaryotes (bacteria) do not contain a nucleus.
Chromesoines
Sodium chloride was needed to ensure the proteins in the cell aren't separated from the rest of the solution with the DNA.
Gel electrophoresis
DNA is soluble in water, but not in salty water. All the other cell contents are soluble in water and saltwater. This difference in solubility allows students and researchers to separate DNA from the rest of the cell.

(APEX) the original DNA strands never being separated.
Often used to purified crude cell lysate by precipitating proteins, lipids and polysaccarides out of solution. This leaves only nucleic acid (DNA, RNA) in the supernatant.

The three biological molecules in the cell that DNA must be separated from are the cell membrane, lipids, and enzymes. The DNA is found in the nucleus of the cell.

The two strands can not be separated mechanically.
