1. Investigation 3 Claims:
Essential Question: How can organisms become mutated? Investigation Question: How are mutations caused by radiation?
Investigation 3 Claims:
Radiation can knock out nucleotides that may cause mutations in DNA. Radiation can cause changes in the operon or section of genes to cause frame-shift or deletion. Radiation may affect the repressor causing the gene to remain in the "ON" position.
Terms of Use:
Mutation, Nucleotides, Frame-shift mutation, Deletion, Hox gene, Repressor, Operon, Radiation

2. How are mutations caused by radiation?
Evidence 3.1
Justification
How does the evidence justify the claim that radiation can knock out nucleotides that may cause mutations in DNA?
Terms:
Mutation, Nucleotides, Frame-shift mutation, Deletion, Radiation

3. How are mutations caused by radiation?
Evidence 3.2
Justification
How does the evidence
justifies the claim that radiation
can cause changes in the
operon or section of genes to
cause frame-shift or deletion?
Terms:
Mutation, Nucleotides, Frame-shift mutation, Deletion

4. How are new genetic combinations made through segregation?
Evidence 3.3
Justification
How does the evidence
justify the claim that radiation may affect the repressor causing the gene to remain in the "ON" position?
Terms:
Mutation, Hox gene, Repressor, Operon, Radiation

5. Investigation Question: How are mutations caused by radiation?
Claim: Radiation can knock out nucleotides that may cause mutations in DNA. Radiation can cause changes in the operon or section of genes to cause frame-shift or deletion. Radiation may affect the repressor causing the gene to remain in the "ON" position. Justification: The claim is supported by evidence because… Evidence: Use the evidence presented (3.1 – 3.3) to justify the claim stated above.
