Lab 2 - Cells & Cell Cycle

Question 1

Cell cycle

Answer 1

All events in the life of a cell from the time the cell forms to the time when it divides and becomes two new cells

Question 2

Parent cell

Answer 2

Cell that divides

Question 3

Daughter cells

Answer 3

Two new cells from parent cell

Question 4

Interphase

Answer 4

Refers to stage of the cell cycle between cell divisions, subdivided into three specific stages (G1, S, G2)

Question 5

G1 Phase

Answer 5

Time when cell is carrying out basic metabolic activity & not preparing to divide

Question 6

S Phase (Synthesis)

Answer 6

Refers to time when cell makes exact copies if its linear DNA molecules in a process called replication or duplication

Question 7

Sister chromatids

Answer 7

Two complete DNA molecules within a replicated chromosome

Question 8

Centromere

Answer 8

Temporarily hold sister chromatids to one another

Question 9

Karyotype

Answer 9

Picture of an organism’s full complement of chromosomes

Question 10

G2 Phase

Answer 10

Represents time when cell is making final preparations for division

Question 11

Mitosis

Answer 11

Process leading up to a parent cell’s replicated, nuclear DNA molecules becoming equally distributed at opposite ends of the cell

(prophase, metaphase, anaphase, telophase)

Question 12

Prophase

Answer 12

Immediately follows G1 of interphase

Question 13

Metaphase

Answer 13

Stage when replicated chromosomes align themselves along the parent cell’s equator

Question 14

Anaphase

Answer 14

Time when sister chromatids separate from one another & move toward opposite poles of the cell

Question 15

Sister chromosomes

Answer 15

Separated chromatids

Question 16

Telophase

Answer 16

Last stage of mitosis when the condensed chromosomes have reached opposite poles of the parent cell & begin to uncoil; new nuclear membrane forms around elongating strands of chromatin

Question 17

Cytokinesis

Answer 17

Final stage of the cell cycle when the parent cell divides to form two daughter cells
