⩥ How does the spindle form? Answer: spindle fibers form a protein
structure that divides the genetic material in a cell
⩥ The centrosome serves as the initiation site for the assembly of.
Answer: microtubles, which grow outward from the centrosome toward
the periphery of the cell
⩥ What is the function of the spindle apparatus? Answer: to help
separate sister chromatids in mitosis by attaching to the centromere of a
duplicated chromosome and pulling sister chromatids to opposite poles
of the cell
⩥ Four stages of mitosis. Answer: prophase, metaphase, anaphase, and
telophase
⩥ Prophase. Answer: 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
, ⩥ Metaphase. Answer: second phase of mitosis, during which the
chromosomes line up across the center of the cell
⩥ Anaphase. Answer: the third phase of mitosis, during which the
chromosome pairs separate and move toward opposite poles
⩥ Telophase. Answer: the final phase of cell division, between anaphase
and interphase, in which the chromatids or chromosomes move to
opposite ends of the cell and two nuclei are formed.
⩥ The cell cycle is regulated by what?. Answer: a molecular control
system that directs the sequential events of the cycle
⩥ How many checkpoints are there in the cell cycle?. Answer: three
⩥ What are the three checkpoints in the cell cycle?. Answer: G1
checkpoint, G2 checkpoint, M checkpoint
⩥ Why are there checkpoints in the cell cycle?. Answer: To check for
errors prior to moving forward
⩥ Cancer. Answer: an error in the cell cycle in which a cell gets past a
checkpoint and divides uncontrollably, forming a tumor
