Chapter 3 Cell Cycle

Question 1

What are the divisions of interphase?

Answer 1

G1, S, G2

Question 2

What happens during interphase?

Answer 2

cell carries on life process, grows, DNA replicates during S-phase

Question 3

What happens during prophase?

Answer 3

nuclear envelope dissolves, chromatin forms into chromosomes, centrioles migrate to poles

Question 4

What happens during metaphase?

Answer 4

chromosomes align at equator of cell, spindle fibers attach to centromeres

Question 5

What happens during anaphase?

Answer 5

spindle fibers shorten, chromatids are pulled toward the poles

Question 6

What happens during telophase?

Answer 6

chromosomes uncoil, nuclear envelope forms around each chromatin mass, cleavage furrow begins to form

Question 7

What happens after cytokinesis?

Answer 7

two new daughter cells are formed, each continues cycle in interphase

Question 8

What divides during mitosis?

Answer 8

the nucleus

Question 9

Where does transcription occur?

Answer 9

in the nucleus; mRNA is made from segment of the DNA template (gene)

Question 10

Where does translation occur?

Answer 10

on a ribosome in the cytoplasm; amino acids are linked together according to the mRNA code
