DNA: Heredity, Structure, Function, and Genetic Applications
Module Summary
This unit gives an introduction to heredity, the structure and function of DNA as well as its use in forensics and other genetic applications. Students will learn how DNA is passed through generations by using paper chromosomes to find the phenotypes and genotypes of parents and offspring. Students then complete multiple labs that concentrate on the structure and function of DNA from the creation of models to DNA extractions. Next students learn the basic techniques needed to work safely and efficiently in a laboratory setting. Finally, students use these techniques and information to solve a crime and discuss controversial topics in genetics.
