Question

select only the events that occur during mitosis and place them in the correct order. the nuclear envelope dissolves and chromatin condenses into chromosomes. the mitotic spindle aligns the chromosomes with the middle of the cell. sister chromatids are separated into individual chromosomes. drag the items below into the box above in the correct order, starting with the first item in the sequence. the chromosome is replicated. the nuclear envelope condenses.

Explanation:

Mitosis has several phases. Prophase is when the nuclear envelope dissolves and chromatin condenses into chromosomes. Metaphase is when the mitotic spindle aligns the chromosomes at the cell - middle. Anaphase is when sister chromatids separate into individual chromosomes. Chromosome replication occurs in interphase (not mitosis) and the nuclear envelope does not condense in the way described.

Answer:

1. The nuclear envelope dissolves and chromatin condenses into chromosomes.
2. The mitotic spindle aligns the chromosomes with the middle of the cell.
3. Sister chromatids are separated into individual chromosomes.
