SAT Cell Division: Mitosis and Meiosis 1

Question 1

Which of the following correctly describes the order of phases in mitosis?

Accepted Answer

Prophase, Metaphase, Anaphase, Telophase

Answer

The correct order of mitotic phases is Prophase, Metaphase, Anaphase, and Telophase, remembered by the mnemonic PMAT.

Question 2

During which phase of mitosis do chromosomes align along the cell's equatorial plate?

Accepted Answer

Metaphase

Answer

During metaphase, spindle fibers attach to centromeres and align chromosomes along the cell's equatorial plate.

Question 3

A human cell with 46 chromosomes undergoes meiosis. How many chromosomes will each resulting cell contain?

Accepted Answer

23

Answer

Meiosis halves the chromosome number, so a diploid cell with 46 chromosomes produces haploid cells with 23 chromosomes.

Question 4

DNA replication occurs during which phase of the cell cycle?

Accepted Answer

S phase

Answer

DNA synthesis (replication) occurs exclusively during the S (synthesis) phase of interphase.

Question 5

What is the primary result of cytokinesis following mitosis?

Accepted Answer

Division of the cytoplasm into two separate daughter cells

Answer

Cytokinesis is the physical division of the cytoplasm following nuclear division, producing two distinct daughter cells.
