blend the watermelon until to break the cell walls, add water if necessary. in a glass, mix 1 tbsp of liquid soap and 2 pinches of salt. the soap will break down the nucleus membrane that encapsulates the DNA. the salt will give an ionic condition necessary (will give positive charge that will neutralize DNA charge). be careful when you mix the soap and salt, you want least amount of bubbles.
add 3 tbsp of the watermelon pulp to the soap mixture, and again, mix carefully because mixing vigorously will break the DNA fragments. filter the mixture with coffee filter. take 5 ml of the filtrate (the liquid, not the pulp in the filter cloth) and using a pipette, drop it to 5 ml of cold ethanol (or isopropanol) 1:1 ratio, if your watermelon is to watery, add more of it. do not mix it, let it sit for some minutes and it will coagulate. the DNA will rise to the top of the ethanol.

What is the hypothesis for strawberry DNA project?
The hypothesis for a strawberry DNA project could be that strawberries contain DNA that can be extracted using household materials and that the DNA extraction process will yield visible strands of DNA.
What is the chemical formula of strawberry extract?
The chemical formula of strawberry extract can vary depending on the specific compounds present in the extract. However, some common compounds found in strawberry extract include sugars like glucose and fructose, organic acids like citric acid, and various volatile compounds that contribute to the aroma of strawberries.
Where is the DNA located in a strawberry?
The most commonly cultivated strawberry, Fragaria ananassa, is an octoploid with eight sets. This makes it a good candidate for demonstrating DNA extraction - with eight copies of each gene in the strawberry genome, strawberries are packed full of it.
Why we can not extract DNA from RBCs?
We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
Do strawberry and human have the same DNA?
There would be more DNA in a strawberry because strawberries are octoploids, they have 8 copies of genes rather than 2 copies found in a cheek cells .
How can one extract DNA from a strawberry?
To extract DNA from a strawberry, you can mash the strawberry, mix it with a salt solution to break down the cell walls, filter out the solid parts, add alcohol to separate the DNA, and then carefully collect the DNA strands using a small stick or pipette.
How could you determine what percentage of a strawberry's mass is DNA?
To determine the percentage of a strawberry's mass that is DNA, you would need to extract the DNA from the strawberry, quantify the amount of DNA extracted, and then divide it by the total mass of the strawberry. This calculation will give you the percentage of the strawberry's mass that is composed of DNA.
Why is strawberry DNA easier to extract then human DNA?
Same nucleic acids, same coding sequences, though many of those sequences are quite variant, same coding for protein products and many coding regions showing the taxonomic linkage, though very far apart, of these two eukaryotic organisms.
What has more DNA strawberry or a kiwi?
a strawberry
Can you use expired strawberry extract?
Yes.
Why is strawberry DNA easier to extract?
It is a polyploid fruit i.e. it has several sets of chromosome complements as a result of scientific intervention. This results in a high DNA content. Also, the pulp is easily broken down meaning the cell walls and membranes can be more readily disrupted thereby releasing more genetic material.
What is the hypothesis for strawberry DNA project?
The hypothesis for a strawberry DNA project could be that strawberries contain DNA that can be extracted using household materials and that the DNA extraction process will yield visible strands of DNA.
How do the enzymes pectinase and cellulase aid in the extraction of DNA from strawberries?
In a strawberry to extract the DNA it is required to break down the cell membrane (both the membrane protecting the cell as well as the membrane protecting the nucleus) and pectinase and cellulase in strawberries are enzymes that are break down these membrane...at least in a strawberry.
Why do strawberry have more DNA than humans?
because they have eight copies of DNA
