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?

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.
Why do you need to extract DNA?
Because it is the only way of life

you must penetrate the nucleus and extract its DNA
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.
