AP BIOLOGY CHAPTER 12 (THE CELL
CYCLE- WRITTEN BY CAMPBELL) EXAM
QUESTIONS AND ANSWERS UPDATED
(2024/2025) (VERIFIED ANSWERS)
Interphase - ANS ✓cell grows, performs its normal functions, and prepares for
division; consists of G1, S, and G2 phases
S phase - ANS ✓The synthesis phase of the cell cycle; the portion of interphase
during which DNA is replicated.
G1 phase - ANS ✓the first gap phase of interphase where the cells do most of
their growing, cells increase in size and make new proteins and organelles
G2 phase - ANS ✓Period of time during interphase--usually the shortest--during
which many of the organelles and molecules required for cell division are
produced (p. 245).
Prophase - ANS ✓first and longest phase of mitosis, during which the
chromosomes become visible and the centrioles separate and take up positions
on the opposite sides of the nucleus

Prometaphase - ANS ✓The second stage of mitosis, in which discrete
chromosomes consisting of identical sister chromatids appear, the nuclear
envelope fragments, and the spindle microtubules attach to the kinetochores of
the chromosomes.
Metaphase - ANS ✓the stage in mitosis in which the duplicated chromosomes
line up along the equatorial plate of the spindle
Anaphase - ANS ✓the third phase of mitosis, during which the chromosome
pairs separate and move toward opposite poles
Telophase - ANS ✓the final stage of mitosis before cytokinesis in which the
separated chromosomes reach the opposite poles of the dividing cell and the
nuclei of the daughter cells form around the two sets of chromosomes
Mitotic spindle - ANS ✓An assemblage of microtubules and associated proteins
that is involved in the movements of chromosomes during mitosis.
Centrosome - ANS ✓Structure present in the cytoplasm of animal cells,
important during cell division; functions as a microtubule-organizing center. A
centrosome has two centrioles.
Kinetochore microtubules - ANS ✓Connects the centrosome with the
kinetochore in the centromere region of the chromosome
