1. Investigation 1 Claims:
Essential Question: How can organisms become mutated? Investigation Question: How do errors occur during DNA replication?
Investigation 1 Claims:
During meiosis the chromosome will copy itself during replication. During DNA replication, no errors can occur after proofreading and mismatch pairing. After replication, the chromosomes will pair up and parts will cross-over to exchange genetic material.
Terms of Use:
Meiosis, DNA Replication, DNA Polymerase, Proofreading, Chromosome, crossing-over, gene, Base Pairing, Mismatch Pairing, Homologous Chromosomes

2. How do errors occur during DNA replication?
Evidence 1.1
Justification
How does the evidence justify the claim that during meiosis the chromosome will copy itself during replication?
Terms:
Meiosis, DNA Replication, DNA Polymerase, Chromosome, Base Pairing

3. How do errors occur during DNA replication?
Evidence 1.2
Justification
How does the evidence
justifies the claim that during
DNA replication, no errors can
occur after proofreading and
mismatch pairing?
Terms: Meiosis, DNA Replication, DNA Polymerase, Proofreading, Base Pairing, Mismatch Pairing

4. How do errors occur during DNA replication?
Evidence 1.3
Justification
How does the evidence
justify the claim that after
replication, the
chromosomes will pair up
and parts will cross-over
to exchange genetic
material?
Terms: Meiosis, crossing-over, gene, Homologous Chromosomes

5. Investigation Question: How do errors occur during DNA replication?
Claim: During meiosis the chromosome will copy itself during replication. During DNA replication, no errors can occur after proofreading and mismatch pairing. After replication, the chromosomes will pair up and parts will cross-over to exchange genetic material. Justification: The claim is supported by evidence because… Evidence: Use the evidence presented (1.1 – 1.3) to justify the claim stated above.
