Which of the following is correctly matched?

Prophase I - Nuclear envelope reforms,nucleolus reappears, spindle apparatus disappears

Metaphase II - Homologous chromosomes align atthe equator (center) of the cell forming tetrads

Anaphase II - Sister chromatids are pulled toopposite poles of the cell by contraction of spindle apparatusmicrotubules

Cytokinesis - Division of the nucleus

Telophase I - Nuclear envelope fragments,nucleolus disappears, spindle apparatus forms
