Cell Cycle Quiz Flashcards
An egg and sperm cell fuse to form a diploid organism (single cell right now). What type of cell cycle event is needed for this organism to grow and develop into a multicellular, complex organism?
Mitosis
Term: Location where replicated chromosomes are attached that spindle fibers can grab on to
centromere
Term: A pair of small organelles that grow spindle fibers
centriole
Term: each half of a replicated chromosome
sister chromatid
Term: Microtubules that elongate and shorten with the goal of moving chromosomes throughout cell division
spindle fibers
90% of a cell’s life is spent in:
Interphase
Right before a cell divides, is DNA found in a chromatin state or a chromosome state?
chromsome
During mitosis, spindle fibers push and pull chromosomes so that they line up along the middle equator of the cell. What is the purpose of the step?
to ensure accurate and organized separation of sister chromatids
A cell has 14 chromosomes. When it divides after mitosis, how many chromosomes will each daughter cell have?
14
During which phase of the cell cycle does the cell grow and carry out normal metabolic functions?
Interphase
What is the purpose of each cell cycle checkpoint? G1 checkpoint
check for existing DNA damage and check status of nutrients
What is the purpose of each cell cycle checkpoint? G2 Checkpoint
check for DNA replication accuracy and size of cell
What is the purpose of each cell cycle checkpoint? Mitosis Checkpoint
check spindles to see if they attached to all sister chromatids properly
