I typed out their method for people who need it for school: 1. Mix the water, salt and dish soap together in a bowl. 2. Place the rubbing alcohol into the freezer to chill. 3. Put 3 strawberries with the stems removed into a Ziplock bag, measure out 3 tablespoons of the previously made solution and pour that into the bag also. 4. Seal the Ziplock bag closed, remembering to remove the air and crush the strawberries until they are a fine, foamy paste. 5. Strain the strawberry pulp into the beaker, using a spoon to push it through. 6.Remove the rubbing alcohol from the freezer and measure out half a cup of it. 7. Gently pour your alcohol into the strawberry mixture, making sure that they don’t mix and that it just makes a fine layer on top of the pulp. This will help the DNA separate from the rest of the strawberry mixture. 8. Use your tweezers to remove the strands of DNA from your beaker.
I have 4 questions for school: 1. What do you think DNA looks like under a microscope? 2. Are strawberries the only fruit with DNA? 3. What does DNA look like in the experiment? 4. Where was the DNA in the strawberry?
I did this experiment at school last year under standard curriculum, and now we're redoing it under honors; I've yet to see the changes implemented for this year in contrast last year, but last year's was pretty similar to this experiment. I don't think our teacher trusted us the tweezers ...
I really appreciate this! So simple and neat! Also I really liked the animated explanation as well, helped a lot for visualizing the process, thanks! Subscribed!
To make it easier for those trying to make a filter. A coffee filter will do as long as your strawberries are squished very thoroughly. H.S. Biology Teacher. Great video!
Bubblegumpop396 If you haven't seen out liquid density tower experiment yet then you should!! You would probably like it, we layer 12 different liquids on top of each other.
Hi Science Guys. Something to ask on. Is the extraction of this experiment can be further use in genome sequence reading? Is the DNA clean from impurity?
Hey Justin, I couldn't reply to your comment directly, probably because your comment is linked. You can do this method with a lot of different fruits. The thing to remember is that if the fruit isn't octoploid you will require much higher quantities of it to get a significant amount of DNA. You might be able to spread the DNA out on a slide and look at it under a strong microscope. You may not see much, but you might see something.
Hey Sci people! I'm doing a science report on this lab exercise and since we're in distance learning I'm using your video as the lab exercise. I was just wondering if you were able to tell me why it is necessary to chill the rubbing alcohol before adding it to the strawberry mixture. if you see this please reply!
The alcohol needs to be cold because it helps increase the yield of DNA. Cells contain enzymes in the cytoplasm that help destroy viruses but protect the DNA. Hot water has the potential to damage DNA by accelerating enzymes that break it apart. DNA is typically protected from such enzymes by the nuclear membrane, but the soap added previously destroys it. Cold alcohol helps the DNA precipitate faster.
Hello, I'm teaching overseas. So i have to rely on locals to buy my supplies. They got ethyl alcohol instead of isopropyl alcohol? Will this still work or should I send them back out for iso? Thanks
Very cool. Will try this out. Is there anything that can be done with the DNA besides just looking at it? Can this method also be used for other fruits or plants?
does anyone know how the greater amount of dna in a strawberry affects the way it functions? for instance, a raspberry has less dna and i’m trying to figure out the way it affects it as a whole.
+The Sci Guys I have a very very important question and i need to know the answer very quickly!

I had a problem with making the layer of alcohol. It made it, but it formed beneath the strawberry mixture. Do you guys know why? (I did pour it gently)
You can use a high proof alcohol (ethanol) and fresh pineapple juice to do this as well. Skip the salt and soap, and instead freeze the strawberries and then let them thaw. Ice crystals will break up the cell membranes (much like the soap). Put about a cup of fresh pineapple juice (not pasteurized) in a baggie with about three strawberries, and squish. Strain the strawberries, and then pour the adult beverage the same way that the rubbing alcohol was done here. The DNA will separate, AND the entire concoction is now made of 100% human consumable ingredients. The Pineapple juice replaces the salt, and the freezing of the strawberries eliminates the need for soap.
In my practice, I put the salt first to smash the strawberrys and then the detergent, actually, i used pineapple juice and i don't know why and i don't find any information of that :'v The result was a little bit of DNA. Could somebody explain that? (notice my terrible english)
Silly question- but would this method work with other materials? Food wise, but also granulated substances such as sand, dust, crushed rock etc. I have to perform this experiment to prove that the provided samples that are not necessarily 'alive, may contain living organisms...not sure if this will work.
Chelssums You can keep it, or observe it under a microscope. Put it in a test tube filled with the remaining alcohol and keep it, or you can let it dry out.

I once tried this on myself by using my saliva instead of the mashed strawberries, and it actually worked!
How much saliva did you use? Probably up to a cup to make your DNA really visible, haha. I only get a dot of DNA from about 2mL of saliva
do it on your blood!!!!!

As a Science teacher, this is one of the more helpful videos for my university students, especially the animation. Keep up the great work.

Thanks for the reasoning part too. Nice lab presentation.
great diagrams and explanation of the reactions - thanks

why put the alcohol in the fridge?

Does the alcohol have be to be cold ?
Very cool. Will try this out. Is there anything that can be done with the DNA besides just looking at it? Can this method also be used for other fruits or plants?
chemistry experinments such as titrations
Would it be an advantage or disadvantage that the strawberry DNA is protected by a two membrane system in the cell?
How would I know if this is really the DNA? Because I don't have any tools to see if it is a real DNA. Thank you!
Gee, Brain, what do you want to do tonight?
The same thing we do every night, Pinky: try to take over the world with strawberry DNA.

How long does it take for the dna to show ?
Is it compulsory to use rubbing alcohol

What substance was used to get the DNA outside of the cell membrane?
Can I use a mortar and pestle instead of a plastic bag?
Is there a certain brand of soap that I should use or is any dish soap applicable?
Does anyone know if this works without cooling the rubbing alcohol before hand?
yea i did this without freezing it beforehand and it worked
Is there anyway i can store this ? My science fair project is next week and I would like to make this today ,how should i store this ?
Yesenia Lopez Just do it twice! it's good to do labs more than once, usually each time you complete a lab you get a little better at it!
I realize your science fair was two years ago... anyway... since I'm quarantined, why not reply. Just pour it in a small container with alcohol.
😂 Teachers sent us here

There won't be enough living organisms to produce visible amounts of DNA

What do you do after? Like how do you read it and test it?

Who else gotta write up about this experiment they did at school but forgot what they did
why does the alcohol need to go into the freezer?
Aurora Lara the DNA itself, while already insoluble in isopropyl, is highly insoluble in chilled isopropyl, thus typically yielding better results
Ah thanks for explaining
this video was made when i most needed it
never mind, wrong year XD lol

What if i put it in a seed
does anyone know why the Isoprophyl Alcohol needs to be in the freezer????
The alcohol needs to be cold because it helps increase the yield of DNA. Cells contain enzymes in the cytoplasm that help destroy viruses but protect the DNA. Hot water has the potential to damage DNA by accelerating enzymes that break it apart. DNA is typically protected from such enzymes by the nuclear membrane, but the soap added previously destroys it.
