Unit 3 Biology I Review

the two new cells that result from mitosis and cytokinesis

• daughter cells
• Spindle
• Anaphase
• Cell Cycle

also known as body cells, these are all the cells in an organism that are different from the X or Y sex chromosomes.

• Somatic cells
• S Phase
• Carcinogens
• Centromere

Substances and agents that are known to cause cancer

• Carcinogens
• Mitosis
• Cell Plate
• Apoptosis

Fanlike microtubule structure that helps separate the chromosomes during mitosis

• Spindle
• Telophase
• Anaphase
• Carcinogens

Programmed cell death

• Apoptosis
• daughter cells
• Mitosis
• Cell Cycle

The period in the cell cycle when the cell is not dividing but growing. Often accounts for about 90% of the cell cycle. During this time, cellular metabolic activity is high, chromosomes and organelles are duplicated, and cell size may increase.

• interphase
• Spindle
• Mitosis
• S Phase

The phase of the cell cycle that includes mitosis and cytokinesis.

• M phase
• daughter cells
• Spindle
• G2 Phase

Area where the chromatids of a chromosome are attached to one another to make the classic " X " shape (in the center of the chromosome)

• Centromere
• Spindle
• Carcinogens
• Anaphase

identical copies of a chromosome; full sets of these are created during the S phase (DNA replication) of interphase

• Sister Chromatids
• Anaphase
• G1 Phase
• Cell Cycle

relaxed form of DNA that makes up chromosomes

• Chromatin
• Telophase
• Spindle
• Cell Cycle
