How to Extract DNA From a Strawberry




Most organisms only have 2 copies of DNA, but a strawberry has 8, so that makes it way easier to get. Enough learning lets blow somethin' up! kidding, lol

Step 1: Meterials

Materials: half a strawberry
                   even 10ml solution of salt,detergent, and water
                   paper towel
                  3ml alcohol

Step 2: Step 1

Put the strawberry half in a bag and seal the bag. Smush the strawberrt until it is mostly smooth. Slowly pour in the 10ml solution of salt, water, and detergent. Tilt bag back and forth until strawberry innards and solution are mixed well. Mix them carefully so you don't get any bubbles. Let it sit so the solution can dissolve cellular membrane.

Step 3: Step 2

place paper towel over cup to act as a filter to get out the strawberry chunks.

Step 4: Step 3

Pour the strawberry mixture through the paper towel

Step 5: Step 4

Let it sit awhile so it can completely drain.

Step 6: Step 5

Remove the paper towel. Now you have pure strwberry solution.

Step 7: Step 6

Pour the juice into a beaker and slowly pour in 3ml of alcohol.

Step 8: Step 7

Stir skewer and extract DNA. Congratulations you are not a pro DNA extracter

    You are absolutely correct....plants have both DNA and RNA.  I stand corrected.  I must have thought I learned that in 8th grade or something.

    Carry on.

    Ill let wikipedia answer that but for a quick answere RNA is not strictly plants
    Ribonucleic acid
    (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate. RNA is very similar to DNA, but differs in a few important structural details: in the cell, RNA is usually single-stranded, while DNA is usually double-stranded; RNA nucleotides contain ribose while DNA contains deoxyribose (a type of ribose that lacks one oxygen atom); and RNA has the base uracil rather than thymine that is present in DNA.

    RNA is transcribed from DNA by enzymes called RNA polymerases and is generally further processed by other enzymes. RNA is central to protein synthesis. Here, a type of RNA called messenger RNA carries information from DNA to structures called ribosomes. These ribosomes are made from proteins and ribosomal RNAs, which come together to form a molecular machine that can read messenger RNAs and translate the information they carry into proteins. There are many RNAs with other roles – in particular regulating which genes are expressed, but also as the genomes of most viruses.

    opps i wrote you are NOT a dna extractor instead of you are NOW a dna extractor sorry people !!
