Extract DNA from a Strawberry

All living things are made of cells and DNA tells the cell what to do. Science Mom shows you how to extract the DNA from a strawberry.

All living things are made of cells and DNA tells the cell what to do. DNA is a polymer, a LONG strand of repeating units. Just like beads strung together make a necklace, nucleotides strung together make a strand of DNA. The long strands are coiled tightly in the nucleus of each cell. Follow along as Science Mom shows you how to extract DNA from a strawberry.

Journal Questions

Why do strawberries and bananas look different?
Did you do the experiment? If so, what was your favorite part? We’d love to see pictures if you took any.
In the video, Science Mom said “if you took one human cell and then stretched the DNA out flat, it would be nearly ___ feet long”. How many feet did she say? What did you think about that? Was it “mind-boggling” to you?
