Lesson 1
What is interphase?
First stage of the cell cycle, during which a cell grows, matures and replicates its DNA.
What is prophase?
First stage of mitosis, during which the cells chromatin condenses into chromosomes.
What is cyclin?
One of the specific proteins that regulate the cell cycle.
What is cell cycle?
The process of cellular reproduction, occurring in three main stages.
What is sister chromatid?
structure that contains identical DNA copies and is formed during DNA replication.
What is carcinogen?
Cancer causing substance.
What is cytokinesis?
Third main stage of the cell cycle, during which the cell's cytoplasm divides, creating a new cell.
What is spindle apparatus?
Structure of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides.
What is stem cell?
Unspecialized cell that can develop into a specialized cell under the right conditions.
What is chromosome?
DNA- containing structure that carries genetic material from one generation to another.
What is anaphase?
Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell.
What is cancer?
Uncontrolled growth and division of cells that can be caused by changes in control of the cell cycle and also maybe caused by environmental factors.
What is mitosis?
Second main stage of the cell cycle during which the cell's replicated DNA divides and two genetically identical diploid daughter cells reproduced.
What is telophase?
Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.
What is cycling-dependent kinase?
Enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle.
