During which phase of chemotherapy do drugs like Asparaginase work?

  1. M phase

  2. G1 phase

  3. S phase

  4. Cell cycle independent

The correct answer is: G1 phase

Asparaginase is a chemotherapy drug that works by targeting cells during the G1 phase. This is the first phase of the cell cycle, where the cell prepares for DNA replication. Targeting cells during this phase can prevent them from growing and dividing, ultimately leading to cell death. Options A, C, and D are all incorrect because they refer to other phases of the cell cycle and indicate that Asparaginase would not be effective during those phases.
