I like this video : ) I’m a double major in Biology at the University of Toronto in my final year, and just did this experiment in one of my labs. We used lab equipment like centrifuges, and micropipettes, and various buffers, but the basic procedure was the same. I didn’t think this could work at home with such basic ingredients and equipment, but this is great!

SHE’S A WITCH!

Well, now, is the dna dissolving into seperate strands, or is it dissolving down to its seperate monomers? If monomers, you’re not really seeing your “dna” pe se so much as clumps of nucleic acids, right.

when its warm the enzyme in it breaks the dna molecules so it doesnt form properly

it actually does work if we just use home things too! my frnds tried it in our colg lab for a project and it came along perfectly!

yea even i had that question…and i think its monomers coz dna that we r seeing cant be in separate strands as it is all clumped together…………….does anyone know how to separate dna into separate strands so that further processing like gene replacement could be done?

yea even i had the same question…i think this dna contains monmers caz after all it is clumped but idk for sure…..
anw does anybody know how to separate dna into individual strands? i really need to know for my science project…..
thanks:)

THANK YOU O MUCH THIS IS PERFECT!

hey dats really cool, i never seen dna

I remember someone telling me that the DNA looks a lot like snot. I should try this experiment.
I wonder if there are any at home experiments someone has done to make recombinant DNA, then used agrobacterium to make a strange hydrid plant.

DNA is in the nucleus you will need a electronic microscope about 300x you can see it i never seen the double helix

Im going to mash up snake venom and inject it into a rat to make a super vermin that will breed and take over the world…

honestly you dont need that many strawberries to extract dna from…I plenty from just 1/2 a strawberry…

hey, i had a lab in my scienc class tday, and you can use wheat germ
December 20th, 2009 at 9:58 pm
youre going to make a super dead rat that’s going nowhere.

i dare you to drink it lawlz jk jk nice vid
January 9th, 2010 at 2:52 pm
see my video…except i didnt do the agrobacterium

to splice you need an endonuclease to splice specific sections of the DNA. Then to view it you need to do a Northern Blot test to see the segmented strands

alcohol does not have an enzyme. it would be call alcoholase if it did
January 9th, 2010 at 2:58 pm
I extracted my own DNA. look at my video

Restriction enzymes (or restriction endonucleases) are useful for chopping up DNA into short fragments – like cutting up a word into smaller letter fragments. Those small fragments can then be compared using gel electrophoresis. You’re probably thinking of a Southern blot, which can be used to test the identity of the actual sequences contained in those fragments (like, is it ACGT or GCTA). A northern blot is very similar but used for RNA.

ya prob. Im doing a thing in research with northern blot and i thought it was used for showing segmented DNA. Thanks for the correction

wow pretty cool

your kitchen looks like my kitchen. LOLz

omg this video is sooooooooo good!!!!! u r very smart i bet!!!! I also was wondering what type of strawberries would have the most DNA is it undder ripe, ripe, or over ripe?
thanks
