Salt helps in breaking the protein chains around the nucleic acids
DNA precipitates in the presence of high salt concentrations (like NaCl) and either ethanol or ispropanol.
Magic
a forensic scientist can extract DNA from all living things and some dead things too
The salt neutralizes the DNA's negative charge with its positive charge while the DNA precipitates.
This is an ambiguous question: are we talking about obtaining DNA samples from the person, are we talking about obtaining DNA from the specimen? Obtaining DNA from a person is as simple as swabbing the person's buccal mucosa, which is inside a person's cheek. Obtaining DNA from a specimen is a process by which DNA is extracted by using chemicals that emulsify the cells to extract the DNA, then centrifuging the mixture to extract it. The DNA is then pipetted into a radioactive gel that identifies each strand's DNA structure. The preparation is then x-rayed to reveal the unique DNA structure.

We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
Salt is used to separate DNA.
Because it is less dense than the alcohol and make it float
si
Yes.
Yes.
You cannot extract gold from salt.
Magic

Because the purpose of this lab is to extract DNA from a variety of cells and see DNA
use nutmeg then sugar with some salt and eat it to become a water ball
