1
Q

Process of cellular Reproduction

A

Cell Cycle

2
Q

Unspecialized cell that can develop into a specialized cell under the right conditions

A

Stem Cell

3
Q

Programmed cell death

A

Apoptosis

4
Q

Cancer-causing substance

A

Carcinogen

5
Q

Uncontrolled growth and division of cells caused by changes in control of the cell cycle and also may be caused by environmental factors

A

Cancer

6
Q

Enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle

A

Cyclin-dependent kinase

7
Q

One of the specific proteins that regulate the cell cycle

A

Cyclin

8
Q

The first stage of the cell cycle, during which a cell grows, matures and replicates its DNA

A

Interphase

9
Q

The second main stage of the cell cycle during which the cell’s replicated DNA divides and two genetically identical diploid daughter cells are produced

A

Mitosis

10
Q

Third main stage of the cell cycle, during which the cell’s cytoplasm divides, creating a new cell

A

Cytokinesis

11
Q

DNA-containing structure that carries genetic materials from one generation to another

A

Chromosome

12
Q

Relaxed form of DNA in the nucleus of a cell

A

Chromatin

13
Q

First stage of mitosis, during which the cell’s chromatin condenses into chromosomes

A

Prophase

14
Q

Structure that contains identical DNA copies and is formed during DNA replication

A

Sister Chromatid

15
Q

Cell structure that joins two sister chromatids

A

Centromere

16
Q

Structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides

A

Spindle Apparatus

17
Q

Second stage of mitosis in which motor proteins pull sister chromatids to the cell’s equator

A

Metaphase

18
Q

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

A

Anaphase

19
Q

Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided

A

Telophase
