Which situation would be the most likely result of a mutation in a eukaryotic organism that causes it to produce less p21 protein than normal? Cells with radiation-induced DNA damage would continue through the cell cycle without repairing the damaged DNA. Cells with incomplete DNA replication would continue through the checkpoint. Cell replication would be slowed due to an increase in active G1/S cyclin-dependent kinase. Cells would not respond to growth factors. Cells would have a hypersensitive response to growth factors.

Question
**Question:**

Which situation would be the most likely result of a mutation in a eukaryotic organism that causes it to produce less p21 protein than normal?

**Options:**

- Cells with radiation-induced DNA damage would continue through the cell cycle without repairing the damaged DNA.

- Cells with incomplete DNA replication would continue through the checkpoint.

- Cell replication would be slowed due to an increase in active G1/S cyclin-dependent kinase.

- Cells would not respond to growth factors.

- Cells would have a hypersensitive response to growth factors.

**Explanation:**

This question explores the potential outcomes of reduced p21 protein production in eukaryotic cells, focusing on the cell cycle and its regulation. The listed options describe various cellular behaviors that could result from impaired p21 function, emphasizing its role in DNA damage checkpoints and cell cycle regulation.
