Question
Can you extract a DNA from a strawberry, if so will you be able to see the DNA without using a microscope?
Purpose
My purpose is to see if the DNA from a strawberry can be extracted by using house hold chemicals.
Research
All living things come with instructions stored in their DNA, short for deoxyribonucleic acid. Whether you are a human, rat, tomato, or bacteria, each cell will have DNA inside of it. DNA is the blueprint for everything that happens inside the cell of an organism, and each cell has an entire copy of the same set of instructions. The entire set of instructions is called the genome.

Scientists study DNA for many reasons. They can figure out how the instructions stored in DNA help your body to function properly. They can use DNA to make new medicines. They can genetically modify foods to be resistant to insects. They can figure out the suspect of a crime. They can even use ancient DNA to reconstruct evolutionary histories!

How do scientists get the DNA out of a cell so that they can study it? This is called a DNA extraction, and there are many DNA extraction kits available from biotechnology companies for scientists to use in the lab. During a DNA extraction, a detergent will cause the cell to pop open, or lyse, so that the DNA is released into solution. Then the DNA can be precipitated out of the solution by adding alcohol. you can make your own DNA extraction kit from household chemicals and use it to extract DNA from strawberries.

All living things have genes, Strawberries, bacteria, humans and all of these genes are made of DNA. That’s why scientists can take a gene from one living thing and put it into another. For example, they can put human genes into bacteria to make new medicines. Strawberries are octoploid, which means they have eight copies of the DNA in their genome in every cell.
