Sample AP Bio FRQ Answer (2023) - Hypothetical Example
Question:
Describe the process of DNA replication in eukaryotic cells and explain how errors during replication are corrected.
Sample Answer:
DNA replication in eukaryotic cells is a complex process that ensures genetic information is accurately copied before cell division. It begins at multiple origins of replication along the DNA molecule, allowing for the simultaneous synthesis of new strands. Key enzymes involved include DNA helicase, which unwinds the double helix, creating replication forks; DNA primase, which synthesizes RNA primers; DNA polymerases, which extend the new DNA strands by adding nucleotides in the 5’ to 3’ direction; and DNA ligase, which seals nicks between Okazaki fragments on the lagging strand.
The process proceeds through several steps:
- Initiation: Multiple origins of replication are activated, and replication forks form.
- Elongation: DNA polymerase synthesizes the leading strand continuously, while the lagging strand is synthesized discontinuously in Okazaki fragments.
- Termination: Replication forks meet, and DNA ligase joins fragments to produce a continuous strand.
Errors during replication, such as misincorporated nucleotides, are corrected primarily through proofreading activity of DNA polymerases and mismatch repair mechanisms. Proofreading involves the exonuclease activity of DNA polymerase, which removes incorrectly paired nucleotides. Mismatch repair detects and repairs errors that escape proofreading by identifying distortions in the DNA helix and excising the mismatched segment, followed by resynthesis.
This multi-layered correction system maintains high fidelity during DNA replication, reducing mutation rates and preserving genetic integrity.
