MCAT 2025: Reproduction Exam 2026
Questions and Answers
What are the 5 cell cycle stages? - Correct answer-G1, S, G2, M, G0
G1 - Correct answer-Cell grows and performs its normal functions. DNA is
examined and repaired.
S - Correct answer-DNA is replicated.
G2 - Correct answer-Cell continues to grow and replicates organelles in
preparation for mitosis. Cell continues to perform its normal functions.
M - Correct answer-Mitosis (cell division) occurs.
G0 - Correct answer-The cell performs its normal functions and is not preparing to
divide.
What are the 4 miotic stages? - Correct answer-Prophase, metaphase, anaphase,
telophase & Cytokinesis
©COPYRIGHT 2025, ALL RIGHTS RESERVED 1
, Prophase - Correct answer-Chromosomes condense, nuclear membrane dissolves,
nucleoli disappear, centrioles migrate to opposite poles and begin forming the
spindle apparatus.
Metaphase - Correct answer-Chromosomes gather along the metaphase plate in the
center of the cell under the guidance of the spindle apparatus.
Anaphase - Correct answer-Sister chromatids separate, and a copy of each
chromosome migrates to opposite poles.
Telophase and Cytokinesis - Correct answer-Chromosomes decondense, nuclear
membrane reforms, nucleoli reappear, spindle apparatus breaks down, cell divides
into two identical daughter cells.
Mitosis - Correct answer-2n --> 2n
Occurs in all dividing cells
Homologous chromosomes do not pair
No cross over
