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

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

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

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

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.
