Practice questions

1 of 50Practice questions for this set
Cells in a tissue are exposed to ionizing radiation that produces double-strand breaks in DNA during G1. A normal G1 checkpoint can delay entry into S phase when DNA damage is detected, preventing replication of damaged templates. In one experimental group, a protein required for the G1 checkpoint is inhibited, so cells enter S phase on schedule even though breaks remain unrepaired. DNA replication proceeds across the genome, and cells later enter G2 with duplicated chromosomes. Which outcome is most likely for these cells as they progress through the cycle?
