Biology Chapter 6 Vocab

Question 1

Cell Cycle

Answer 1

Process of cellular reproduction, occurring in three main stages – interphase (growth), mitosis (nuclear division), and cytokinesis (cytoplasm division).

Question 2

Chromatin

Answer 2

Relaxed form of DNA in the nucleus of a cell.

Question 3

Chromosome

Answer 3

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

Question 4

Cytokinesis

Answer 4

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

Question 5

Interphase

Answer 5

First stage of the cell cycle during which a cell grows, matures, and replicates DNA.

Question 6

Mitosis

Answer 6

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

Question 7

Anaphase

Answer 7

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 cells.

Question 8

Centromere

Answer 8

Cell structure that joins two sister chromatids.

Question 9

Metaphase

Answer 9

Second Stage of mitosis in which motor proteins pull sister chromatids to the cells equator.

Question 10

Prophase

Answer 10

First stage of mitosis, during which the cells chromatin condenses into chromosomes.

Question 11

Sister Chromatid

Answer 11

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

Question 12

Spindle Apparatus

Answer 12

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

Question 13

Telophase

Answer 13

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