Question

1. what holds the chromatids together?
2. when do the sister chromatids separate?
3. during which phase do chromosomes first become visible?
4. during which phase does the cleavage furrow start forming?
5. what is another name for mitosis?
6. complete the following table by checking the correct column for each statement.

statement	interphase	mitosis

|nuclear division occurs|
|chromosomes are finishing moving into separate daughter cells|
|normal function occurs|
|chromosomes are duplicated|
|dna synthesis occurs|
|cytoplasm divides immediately after this period|
|mitochondria and other organelles are made|

Explanation:

• Nuclear division occurs: Mitosis is the process of nuclear division.
• Chromosomes are finishing moving into separate daughter cells: This happens in telophase of mitosis.
• Normal function occurs: Interphase is when the cell is in its normal functioning state (G1 phase).
• Chromosomes are duplicated: This occurs in S - phase of interphase.
• DNA synthesis occurs: S - phase of interphase is for DNA synthesis.
• Cytoplasm divides immediately after this period: Cytokinesis (cytoplasmic division) occurs after mitosis.
• Mitochondria and other organelles are made: This occurs in G1 phase of interphase.

Answer:

Statement	Interphase	Mitosis
Chromosomes are finishing moving into separate daughter cells		√
Normal function occurs	√
Chromosomes are duplicated	√
DNA synthesis occurs	√
Cytoplasm divides immediately after this period		√
Mitochondria and other organelles are made	√
