Interphase

Answer 2

period of the cell cycle between cell divisions

Cytokinesis

Answer 5

Division of the cytoplasm during cell division

Answer 7

protein molecule around which DNA is tightly coiled in chromatin

Question 8

Zygote

Answer 19

Fertilized egg

Question 20

tumor suppressor gene

Answer 20

a gene that codes for regulator proteins that prevent the cell from undergoing uncontrolled division

Question 21

Photo-oncogene

Answer 21

Genes that encourage cell division.

Question 22

Mutation

Answer 22

A rare change in the DNA of a gene, ultimately creating genetic diversity.

Answer 24

Cancer causing mutagen.

Question 25

sister chromatid

Answer 25

one of a pair of identical chromosomes created before a cell divides

Question 26

Prophase

Answer 26

Chromatin condenses into chromosomes

Question 27

Metaphase

Answer 27

Chromosomes line up in the middle of the cell

Question 28

Anaphase

Answer 28

Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell

Question 29

Telophase

Answer 29

the final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle

Question 30

asexual reproduction

Answer 30

Process by which a single parent reproduces by itself
