Question

starting with the events of interphase, place events in sequence.
chromosomes replicate
animal cells elongate
chromosomes are maximally condensed
chromosomes coil/condense
nuclear envelope breaks apart
spindles form
nuclear envelope reforms
sister chromatids separate
reset

Explanation:

• Interphase: Chromosomes replicate during the S - phase of interphase.
• Prophase: Chromosomes coil/condense, spindles form, and the nuclear envelope breaks apart.
• Metaphase: Chromosomes are maximally condensed and line up at the metaphase plate.
• Anaphase: Sister chromatids separate.
• Telophase: Nuclear envelope reforms.
• Cytokinesis (for animal cells): Animal cells elongate as part of cytokinesis.

Answer:

1. Chromosomes replicate
2. Chromosomes coil/condense
3. Spindles form
4. Nuclear envelope breaks apart
5. Chromosomes are maximally condensed
6. Sister chromatids separate
7. Nuclear envelope reforms
8. Animal cells elongate
