The most common uses of extracted DNA include:
- amplifying a small amout of DNA (or small sequence) into an enormous amount
- mutating a particular DNA sequence into something more interesting
- probing the DNA for known sequences
- digesting the DNA into little pieces in order to analyze them
Extracting DNA from cells is one of the first steps of one of the most commonly used procedures in molecular Biology: Polymerase Chain Reaction (PCR). Separating the DNA from the rest of contents of the cell makes for a cleaner result, but nowadays it's not strictly required.
Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with Diabetes can live longer.

Where can forensic scientist extract DNA from in a crime scene?
a forensic scientist can extract DNA from all living things and some dead things too
What are the 4 steps used to extract DNA?
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.
Why do scientists extract DNA?
Scientists might extract DNA for many reasons. In a homicide case, or a case in which an unidentified body has been found, scientists extract DNA from the bones (if only bones are found) to identify Null. To check for birth defects in humans or animals. *In an unidentified creature, scientists will want to check all deails *etc.
How does salt soap and ethanol extract DNA?
DNA precipitates in the presence of high salt concentrations (like NaCl) and either ethanol or ispropanol.
Why we can not extract DNA from RBCs?
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.

Purpose of pepsin in DNA extract?
Pepsin is an enzyme that catalyzes the breakdown of proteins into polypeptides and amino acids through hydrolysis. In DNA extraction, this proteolytic processing is essential in dissolving the cellular and histone proteins that bind the DNA strands.
What is the purpose of incubation in DNA extraction?
This is to give a period of time for the DNA to grow by replication; this allows there to be enough of a sample of DNA to extract.
Why do you need to extract DNA?
Because it is the only way of life
How do you temper in an egg?
you must penetrate the nucleus and extract its DNA
