DNA can be separated from the rest of the lysate through a process called DNA extraction. This typically involves breaking open the cells to release the DNA, then using various methods such as precipitation or column purification to isolate the DNA from other cellular components like proteins and lipids. Once the DNA is separated, it can be further purified and analyzed for various molecular Biology applications.

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.

When alcohol is added to denatured DNA, a white stringy precipitate of DNA will form. The DNA precipitates out of the solution because of its insolubility in alcohol, allowing it to be separated from the rest of the solution.
Gel electrophoresis
70% ethanol is used in DNA extraction to wash and precipitate DNA from a sample. Ethanol helps to remove impurities and salts, allowing DNA to clump together and be easily separated from the rest of the sample. It also helps to preserve the integrity of the DNA during the extraction process.

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.
Salt helps to neutralize the charges on the DNA phosphate backbone and the proteins present in the cell lysate, allowing DNA molecules to clump together and precipitate out of solution. This step helps to separate DNA from other cellular components during the extraction process.
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 junction between separated strands of DNA is called a replication fork.

The three biological molecules in the cell that DNA must be separated from are proteins, RNA, and lipids. This separation is essential for processes like DNA replication, transcription, and translation to occur efficiently and accurately.
