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.
Scientific research like molecular Biology or forensic analyses allows for the extraction of the DNA.
Exract the DNA from the srawberry.....
Gel chromatography
you don't.
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.
what is it
Yes. A strawberry is an organism; thus, it contains 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 .
Pepsin is an enzyme that catalyzes the breakdown of proteins into polypeptides and amino acids through hydrolysis. In DNA extraction, this proteolytic processing is essential in dissolving the cellular and histone proteins that bind the DNA strands.
Divide the weight of the strawberry's DNA by the strawberry itself.
a strawberry
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.
Yes.

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.

Yes. A strawberry is an organism; thus, it contains DNA.
because they have eight copies of DNA
si
Yes.
Yes.
