Ch. 9 Test Review

The process in which cells grow and divide is called the _______.

• Mitosis

• Meiosis

• Division

• Cell Cycle

​ (a)   is the stage of the cell cycle in which the cell grows, carries out cellular functions, and replicates (makes copies of) its DNA to prepare for the next stage of the cell cycle.

• Interphase
• M1
• G
• M2

​ (a)   is the stage of the cell cycle during which the cell's nucleus and nuclear membrane divide.

• Mitosis
• G2
• Meiosis
• G1

Match the following.

• Prophase

• The structures that contain identical DNA (HINT: they are each half of the "X" of the chromosomes.

• Chromatin

• Structures that contain the genetic material that is passed on from generation to generation.

• Chromosomes

• Relaxed form of DNA inside the cell's nucleus.

• Cytokinesis

• The process by which the cell's cytoplasm divides.

• Sister chromatids

• The first and longest stage of mitosis, in which chromatin condenses into chromosomes.

The structure at the center of the chromosome where the sister chromatids are attached is called the ​ (a)  

• centromere
• chromatin
• chromatid
• chromosome

The second phase of mitosis, in which the chromosomes line up in the center of the cell, is called _________.

• Prophase

• Metaphase

• Anaphase

• Telophase

The third phase of mitosis, in which the spindle fibers pull apart the chromatids, is called​​ (a)  

• Anaphase
• Prophase
• Metaphase
• Telophase

The last phase of mitosis, in which chromosomes arrive at the poles of the cell and relax, is called ​ (a)  

• Telophase
• Prophase
• Metaphase
• Anaphase

Proteins called ​ (a)   bind to cyclin-dependent kinases (CDKs) during interphase and mitosis to start the activities that take place during areas of the cell cycles.

• cyclins
• kinases
• carcinogens
• leptins

​ (a)   is the uncontrolled growth and division of cells (a failure to regulate the cell cycle).

• Cancer
• Carcinogens
• Cyclins
• Chromosomes
