AP BIOLOGY EXAM (UNITS 5-8) 2025
QUESTIONS AND ANSWERS
CELL CYCLE
interphase, mitosis, cytokinesis - ANS cell cycle stages
G1 phase, S phase, G2 phase - ANS interphase
The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before
DNA synthesis begins. - ANS G1 phase
The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated. -
ANS S phase
The second growth phase of the cell cycle, consisting of the portion of interphase after DNA
synthesis occurs. - ANS G2 phase

,part of eukaryotic cell division during which the cell nucleus divides
-prophase, metaphase, anaphase, telophase - ANS Mitosis
Chromosomes become visable, nuclear envelop dissolves, spindle forms - ANS prophase
Chromosomes line up in the middle of the cell - ANS Metaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell -
ANS anaphase
After the chromosome seperates, the cell seals off, Final Phase of Mitosis. - ANS telophase
division of the cytoplasm to form two separate daughter cells - ANS Cytokinesis
A nondividing state occupied by cells that have left the cell cycle, sometimes reversibly. -
ANS G0 phase

, control mechanisms in eukaryotic cells which ensure proper division of the cell
G1, S, G2, M - ANS cell cycle check points
checks for cell size, nutrients, growth factors and DNA damage - ANS G1 checkpoint
checkpoint that determines if DNA has been replicated properly - ANS S checkpoint
checks for cell size and DNA replication - ANS G2 checkpoint
Spindle assembly checkpoint. Mitosis will not continue if chromosomes are not properly
aligned. - ANS M checkpoint
mitosis promoting factor - ANS MPF
two types of regulatory proteins involved in cell cycle control - ANS cyclins and cyclin-
dependent kinases (cdks)
