During which phase of mitosis do the nuclear envelope, nucleolus, and endoplasmic reticulum reform around the daughter nuclei?
Answer and explanation
Correct answer: C. Telophase
- Step 1: Telophase is essentially the reverse of prophase.
- Step 2: As separated chromosomes reach the opposite spindle poles, they uncoil and decondense into diffuse euchromatin and heterochromatin.
- Step 3: Nuclear lamins dephosphorylate, guiding the assembly of a new nuclear envelope around each chromosomal cluster; nucleoli, the Golgi apparatus, and the ER reappear.
Answer
Telophase.
Why not the others: Metaphase is the stage of maximum condensation where chromosomes align at the equator; Anaphase is the stage of rapid poleward chromatid segregation; Early prophase is when organelles disassemble.
