Question

part a assessments
complete the table by listing the major events of each phase in the second column.

phase	major events occurring
mitosis prophase
metaphase
anaphase
telophase
cytokinesis

Explanation:

Interphase: Cell growth and DNA replication. G1 - cell grows and prepares for DNA synthesis, S - DNA replicates, G2 - cell prepares for mitosis.
Prophase: Chromatin condenses into chromosomes, nuclear envelope breaks down, spindle fibers form.
Metaphase: Chromosomes line up at the cell's equatorial plate.
Anaphase: Sister chromatids separate and are pulled to opposite poles of the cell.
Telophase: Chromosomes reach poles, nuclear envelopes reform, chromosomes de - condense.
Cytokinesis: Cell divides into two daughter cells, in animal cells a cleavage furrow forms, in plant cells a cell plate forms.

Answer:

Phase	Major Events Occurring
Mitosis - Prophase	Chromatin condenses to chromosomes, nuclear envelope breaks down, spindle fibers form
Metaphase	Chromosomes line up at equatorial plate
Anaphase	Sister chromatids separate and move to opposite poles
Telophase	Chromosomes reach poles, nuclear envelopes reform, chromosomes de - condense
Cytokinesis	Cell divides into two daughter cells (cleavage furrow in animal cells, cell plate in plant cells)
