Chapter 8: Cell Division

Question 0

Haploid

Answer 0

A cell that only contains a single set of chromosomes and therefore only a single set of genes

Question 1

Diploid

Answer 1

A cell that contains both sets of homologous chromosomes

Question 2

Anaphase

Answer 2

When chromosome pairs separate and move toward opposite poles

Question 3

Asexual reproduction

Answer 3

When a single parent reproduces itself

Question 4

Cell cycle

Answer 4

Series of events that cells go through as they grow and divide

Question 5

Cell division

Answer 5

When a cell divided into two daughter cells

Question 6

Centromere

Answer 6

Area where the chromatids of a chromosome ate attached

Question 7

Crossing over

Answer 7

When homologous chromosomes exchange portions of their chromatids during meiosis

Question 8

Cytokinesis

Answer 8

Division of the cytoplasm during cell division

Question 9

Daughter cell

Answer 9

Cells formed through mitosis that contain DNA from parent cells

Question 10

Fertilization

Answer 10

When a male and female reproductive cells join to form a zygote

Question 11

Gamete

Answer 11

Specialized cell involved in sexual reproduction( egg and sperm)

Question 12

Independent assortment

Answer 12

Independent segregation of genes during the formation of gametes

Question 13

Interphase

Answer 13

Period of the cell cycle between cell division

Question 14

Metaphase

Answer 14

When chromosomes line up across the center of the cell

Question 15

Mitosis

Answer 15

Part of eukaryotic cell division where the cells nucleus divides

Question 16

Nondisjunction

Answer 16

Error in meiosis in which homologous chromosomes fail to separate

Question 17

Parent cell

Answer 17

A cell that combines genetic info with another cell to form a zygote in meiosis

Question 18

Prophase

Answer 18

When the chromosomes become visible and the centrioles separate and go to opposite sides of the cell

Question 19

Sexual reproduction

Answer 19

Cells from 2 different parents unite to produce the first cell of an organism

Question 20

Sister chromatids

Answer 20

2 Chromatids that are held together by a centromere to form a chromosome

Question 21

Telophase

Answer 21

When the chromosomes begin to disperse into a tangle of dense material.

Question 22

Cancer

Answer 22

the disease caused by an uncontrolled division of abnormal cells in a part of the body.

Question 23

Cyclins

Answer 23

one of a family of closely related protiens that regulate the cell cycle in eukaryotic cells

Question 24

External regulator

Answer 24

Proteins that respond to events outside the cell

Question 25

Gene linkage

Answer 25

certain genes tend to be inherited together, because they are on the same chromosome. Thus parental combinations of characters are found more frequently in offspring than nonparental.

Question 26

Gene map

Answer 26

(2) A map of the relative positions of genetic markers along a chromosome of a particular species as determined by the recombination frequency during crossover of homologous chromosomes.

Question 27

Internal regulator

Answer 27

Proteins that respond to events inside the cell

Question 28

Meiosis

Answer 28

The process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes Ina diploid cell
