Continuum of Activities
The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.
This continuum of activities offers:
- Instructional activities designed to be integrated into planned lessons
- Questions/activities that grow in complexity
- Opportunities for differentiation for each student’s level of performance
Activities
- A mutation is a change in what cellular molecule?
- What type of mutation occurs when a part of the DNA is removed?
- What type of mutation occurs when a part of the DNA is added?
- What type of mutation occurs when a base replaces another base?
- An individual could end up with an extra chromosome and survive. Explain how this could occur and name a condition that is a result of such a change.
- Individuals with red hair are often born with curly hair. Explain the possible relative location of these two genes. Explain what could have occurred (excluding a mutation) in order to get an individual with red straight hair.
Answer Key/Rubric
- DNA
- Deletion
- Insertion or addition
- Substitution
- Acceptable answers include, but are not limited to:
- This is known as non-disjunction, where a chromosome does not separate from its copy and the individual inherits both.
- Downs Syndrome is an example.
- Acceptable answers include, but are not limited to:
- The two genes are most likely on the same chromosome and are located close to one another. This accounts for the occurrence of both genes being inherited together. For someone to have red straight hair, crossing over could have occurred and the genes could have been mixed up.
