1. Warm-up:Mutations How do genetic mutations affect the evolution of organisms?

2. What Are Mutations?
Changes in the nucleotide sequence of DNA

4. Standard S7L3: Recognize how biological traits are passed on Learning Target: Today, students will be able to describe how genetic mutations affect the evolution of organisms?
