Topics Covered

This section test covers the cellular process of mitosis. MCAT takers should be confident in the steps of mitosis and how it compares to other possible replication modes (meiosis, binary fission, etc).

Section Test

1. Which of the following is true regarding the genetic material replicated during mitosis of a diploid cell?

It involves transcription of the cell's DNA
It results in two haploid daughter cells
During mitosis DNA replication occurs such that each daughter gets a copy of the genome
It results in daughter cells who are genetically identical, but physically smaller than the original cell

2. During mitosis, crossing over (the swapping of segments of DNA between homologous chromosomes) ______________.

never occurs.
occurs under special circumstances or in special cell types like somatic cells.
occurs and is a normal part of mitosis.
none of the above.

3. During which stage does DNA replication occur?

Prophase
Anaphase
Telophase
none of the above.

4. What is the function of the centrioles?

The cause cytokinesis die to the concentric shortening of microtubles
They produce microtubles for the chromosomes to migrate along as they move in opposite directions
They hold the two daughter chromatids together at the centromere
They are remain at the center of the cell during mitosis and divide the cell in two halves

5. Which series provides the correct/proper order of mitotic events?

metaphase, anaphase, prophase, telophase
prophase, telophase, anaphase, metaphase
prophase, metaphase, anaphase, telophase
anaphase, prophase, metaphase, telophase

6. Which sequence correctly orders all the stages of the cell cycle (all mitotic steps are included in M) terminating at an arrested/ fully differentiated cell?

G1, S, G2, M, G0
G0, G1, G2, S, M
S, G0, G1, G2, M
S, M, G0, G1, G2

7. Mitosis is most like

sexual reproduction
meiosis
binary fission
yeast budding

8. The step of mitosis in which chromosomes are completely aligned is _______.

telophase
metaphase
prophase
anaphase

9. The step of mitosis in which chromosomes shorten and condense is _______.

metaphase
telophase
anaphase
prophase

10. The step of mitosis in which centrioles pull chromatid and repel each other with microtubles is ________.

prophase
telophase
metaphase
anaphase

11. Cytokinesis is associated with which mitotic step?

anaphase
prophase
telophase
metaphase
