Question

Your goal is to use the DNA Extraction protocol that you have designed to carry out your own DNA extraction experiment. Before you conduct this experiment, you may want to practice it first.  

Now that you've either successfully learned about extracting DNA and coming up with a protocol from one source, you're ready to experiment further. Come up with your own experimental plan. Your experimental plan may involve one of these following ideas or your own creative questions. There are all sorts of cell types that you could think about isolating DNA from for this experiment.

Potential Ideas:

Experiment with other DNA sources. Which source gives you the most DNA? How can you compare them?

Experiment with different soaps and detergents. Do powdered soaps work as well as liquid detergents? How about shampoo or body scrub?

Experiment with leaving out or changing steps. We've told you that you need each step, but is this true? Find out for yourself. Try leaving out a step or changing how much of each ingredient you use.

Do only living organisms contain DNA? Try extracting DNA from things that you think might not have DNA.

Now that you have decided what you will do, carry out this experiment and submit the results via your experimental plan. Do not forget to document everything !

Explanation / Answer

Ans 1:- DNA can be extracted from virtually any part of human body. The most common source of DNA is blood or soft tissue samples, Blood is an excellent source of human DNA. DNA is present in white blood cells of humans, but not red blood cells, which lack nuclei.DNA can be also extracted from semen, saliva, hair roots and even from several skin cells left on the surface of a pint glass after it was touched.There are various methods by which the DNA can be compared they are as Gel Electrophoresis, Real-time PCR, Statistical Analysis, Large-Scale Application, Long-Term DNA Storage and Microarray Genotyping,Spectrophotometric measurements etc
