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

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

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

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

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.
