Strawberry DNA Extraction

Strawberry DNA Extraction is a fun experiment that you can perform using everyday materials. The purpose of this experiment is to develop the interest, knowledge and skills of our students in the areas of biotechnology and life sciences. It engages students with a hands-on activity that is fun, interesting and informative and that can be used with a variety of levels from grade school to high school by tailoring the complexity of accompanying material.

@minyingfeng Yes, I believe so. Kiwi's, Banana's, Strawberry's, and maybe lemons and oranges.

can it be 50% lsopropyl

[minyingfeng]

does this method work on other fruits?

This lab does work, the soap breaks down the lipid bilayers in the cells.

@thatAWES0MEdude I did this in 6th grade

[thatAWES0MEdude]

what grade level is this?

I did this today in class except my class used the inside of our cheeks and swished salt water for 1 minute spit out into cup, added dish soap, stirred very gently with and extended paper clip for 10 sec., and waited 1 more minute. Added some rubbing alcohol by sucking it into a eyedropper and let it pour out slow and gently. Waited 5 minutes. took same paperclip and pulled out the DNA, which our teacher said, is supposed to look like clear snot.

@Dinocrap1101 Well, apparently the soap breaks down the phospholipid bi layer that forms the nuclear envelope because it's formed from fat and the soap eats that away. After the envelope is broken down, the genetic material is released from the nucleus. The salt helps bind it together. If you carefully introduce the alcohol it creates the interface where the genetic material rises up to. Might be fake, but it does sort of make sense. Too bad you can't see it with a super high powered scope!

@elanajoy86 It just seems to me after all my studies on what DNA actually is i sincerely doubt this is a successful method of extracting it, from anything.

@Dinocrap1101 I did this in Bio this semester at my university, it's real.
