Before a body cell divides, which event during interphase ensures that each daughter cell can receive a complete set of genetic material?
Correct answer: A. Replication of DNA
- A. Replication of DNA
- B. Destruction of the nucleus
- C. Secretion of digestive enzymes
- D. Fusion of two daughter cells
Explanation
DNA replication occurs during interphase before mitosis, producing a copy of each chromosome for the future daughter cells. The nucleus is not destroyed as a preparatory step, and daughter cells do not normally fuse.
