DNA—just about everyone has heard of it. Most people know that DNA can be used to solve crimes or determine paternity. Many DNA testing kits are available commercially, offering the ability to trace ancestry or predict the risk of developing certain illnesses. But do you have a thorough understanding of what DNA is or the fundamental role it plays in all living things?
In this module, students will learn about the structure of DNA and its location in living cells. They will learn how DNA is organized into discrete units of heredity called genes, and learn how genes are expressed through the processes of transcription and translation. Finally, they will learn how DNA mutations occur and will discover how mutations in cellular DNA can lead to diseases (such as Sickle Cell Anemia, Cystic Fibrosis, Tay-Sachs disease, and cancer). Periodic quizzes (fact checks) will test students’ understanding before moving forward. Many activities are provided to give students practice in DNA base-pairing rules, transcription, and using the codon table to translate mRNA into protein. Directions for 2 labs are included which can each be performed using household materials.
