The DNA Extraction lab is an activity developed to help student explore the scientific method. Students will extract DNA from a plant to determine whether or not it’s fruit is biotic.
All living things are made of cells. Most cells contain deoxyribonucleic acid, or DNA, the blue print of all living things. In prokaryotes (single-celled organisms such as bacteria), the DNA is floating freely in the cytoplasm of the cell. In eukaryotes (multi-celled organisms), the DNA is enclosed within a nucleus. DNA contains the genetic code needed to synthesize proteins.
Students will be able to
- Differentiate between biotic and abiotic factors
- Identify the different components of a eukaryotic cell
- Illustrate the different components of DNA
- Extract DNA from a fruit
- Outline the steps of the scientific method
