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
- What is the process of copying DNA called?
- Where in the cell does DNA replication occur?
- When DNA replicates, what bases would pair with the following sequence of DNA nucleotides: Adenine, Cytosine, Guanine, and Thymine.
- If mutated or damaged DNA was replicated what would result?
- When looking at a double stranded molecule of DNA, what can be said about the ratio of Adenine to Thymine bases and why?
- If a high temperature changed the shape of the DNA polymerase, what effect would this have on the cell?
- DNA at the ends of a chromosome are very difficult to copy. There is a special enzyme called Telomerase that is used in this area. Telomerase is often switched off in adult cells; however, in cancer cells telomerase may be activated. Explain the actions of telomerase in cancer cells.
Answer Key/Rubric
- Replication
- The nucleus
- Thymine, Guanine, Cytosine, Adenine.
- Acceptable answers include, but are not limited to:
The copy of DNA would also be damaged. - Acceptable answers include, but are not limited to:
There would be an equal number of Adenine and thymine bases because they pair up together. - Acceptable answers include, but are not limited to:
DNA replication would not occur because the DNA would not have new nucleotides attached to the DNA. - Acceptable answers include, but are not limited to:
In cancer cells the enzyme telomerase would most likely be activated which would make the cells divide uncontrollably.
