bio 3 exam

Question 1

prophase

Answer 1

chromosome start to condense, spindle starts to form, nuclear envelope starts to dissociate

Question 2

prometaphase

Answer 2

nuclear envelope completely disassociates, spindle formed, and attach to kinetochores on chromosomes.

Question 3

metaphase

Answer 3

sister chromatids align

Question 4

anaphase

Answer 4

chromatids separate, individual chromes move to poles

Question 5

telophase and cytokinesis

Answer 5

nuclear envelope forms, cell separates into 2

Question 6

G1

Answer 6

growth

Question 7

s phase

Answer 7

chromes replicate and make sister chromes (DNA synthesis)

Question 8

G2

Answer 8

growth and preparation for mitosis

Question 9

mitosis

Answer 9

cell division

Question 10

meiosis: prophase 1

Answer 10

chromosome pairs match up (homologous pairs)

Question 11

meiosis: metaphase 1

Answer 11

homologous pairs line up next to each other and then line up end to end

Question 12

anaphase 1

Answer 12

spindle fibers pull apart chromes (chromatids still intact

Question 13

meiosis 2

Answer 13

basically same steps as mitosis
