Removing Hair dna?

Question

I have a science fair project due in about 2 months. and I need help on finding how to remove dna from hair!! I can't find any articles on it at all!! Can someone find me a website or tell me how to!!!

Answer 1

Hydrogen Peroxide

Answer 2

There is no DNA in hair itself because hair is not made of cells. They are made of protein. There is some cells on the roots of hair, but there's only few cells there, so you won't have enough DNA to do much with it. People who use hair roots for DNA analysis would take the DNA from the hair and amplify them (make many copies) before they can use it for analysis.

If you want to extract your own DNA, you can use your cheek cells. All you need to do is rinse your mouth with some water and spit it into a cup. There are lots of cheek cells in that. With some salt water, dish detergent and ethyl alcohol, you can extract your own DNA. Its not pure DNA because your DNA has lots of protein associated with it, but you can actually spool it out. It will look like very delicate thin white strands.

I do this as a lab with my biology class. The last link in the list below is the handout I created for my students to do the lab. The first two are ones I just found on the internet after I did a google search "isolate your own DNA"

Answer 3

Wow, three for three on not very good answers.

It is actually very simple, and something that I used to do as a lab with my intro to college bio labs.

All you need is a dilute solution of lye. Typically I use 25mM. Heat it to 95 for 30 minutes with your hair roots ( you must have the roots), then neutralize with 40mM Tris.

You won't get very much at all, so you will have to use PCR if you want to do fingerprinting, etc.

Isn't removeing DNA illeagal?
