Cell Cycle

The​ cell ​ (a)   is a​ (b)   of several phases through which a cell passes as it ​ (c)   , prepares for ​ (d)   , and ​ (e)   .

• cycle

• sequence

• grows

• division

• divides

Reorder the steps in the cell cycle.

• G1 Phase - Cell undergoes rapid growth

• S - Synthesis Phase (DNA Replication)

• G2 Phase - cell prepares for mitosis. Shortest phase, but it is when most of the molecules needed for cell division are produced.

• Mitosis - is the process in which a nucleus divides to form two nuceli.

• Cytokinesis - cell division in which the cytoplasm divides

• The timing and rate of cell division is controlled by a combination of two substances: 

• proteins called​ ​ (a)   bind to enzymes called ​ (b)   during interphase and mitosis

• cyclins

• cyclin-dependent kinases (CDKs)

• carcinogens

• centromeres

• spindle fibers

• aster fibers

• centrioles

• motor proteins

• microfilaments

• The cell cycle has built in checkpoints that monitor the cell cycle and can stop it if something goes wrong: 

  • near the end of the​ (a)   stage of ​interphase , a checkpoint monitors for DNA damage and can stop the cycle before entering the ​ (b)   stage of interphase
