Module 5

Question 1

mitosis

Answer 1

occurs in somatic cells and single celled organisms to form two daughter nuclei genetically identical to the parent cell and each other

Question 2

meiosis

Answer 2

occurs in multicellular organisms in preparation for sexual reproduction
two nuclear divisions and four haploid daughter cells

Question 3

interphase

Answer 3

cell growth and DNA synthesis

cells spend majority of time in this stage

Question 4

G1

Answer 4

increase in size, produce RNA, and synthesize protein

Question 5

S

Answer 5

cell’s genetic material is replicated

Question 6

G2

Answer 6

cell continues to grow

Question 7

prophase

Answer 7

Nuclear envelope breaks

chromosomes become more compact

Question 8

prometaphase

Answer 8

spindle forms and start to attach to the chromosomes

Question 9

metaphase

Answer 9

chromosomes move to the middle region between each pole

Question 10

anaphase

Answer 10

centromeres of each sister chromatid separate and forms daughter chromosome

move to opposite poles of the spindle

Question 11

telophase

Answer 11

nuclear envelope reforms; spindles dissolve, chromosomes decondense

Question 12

cytokinesis

Answer 12

division of the cytoplasm; cleavage furrow forms at the equator

Question 13

prophase 1

Answer 13

chromosomes condense and nuclear envelope dissolves; crossing over occurs; tetrad

Question 14

prometaphase 1

Answer 14

spindle apparatus forms and attaches to chromosome

Question 15

metaphase 1

Answer 15

chromosome pairs line up at the middle

Question 16

anaphase 1

Answer 16

homologous pairs separate and each chromosome is pulled to opposite poles

Question 17

telophase 1

Answer 17

chromatin becomes somewhat uncoiled and nuclear envelope reforms

Question 18

prophase ii

Answer 18

chromosomes condense again and nuclear envelope dissolves

Question 19

prometaphase ii

Answer 19

spindle forms and attach to chromosomes

Question 20

metaphase ii

Answer 20

chromomes line up in middle

Question 21

anaphase ii

Answer 21

chromosomes separate and become daughter chromosomes and move to opposite poles

Question 22

telophase ii

Answer 22

four haploid cells
