Cell Cycle

Question 1

Chromosomes

Answer 1

tightly bundled chromatin used to transmit genetic information from one cellular generation to the next

Question 2

Chromatin

Answer 2

the DNA and associated proteins found in the nucleus of a cell

Question 3

Karyotype

Answer 3

display of an individual’s chromosomes often used prior to birth to detect potential birth defects

Question 4

Sister Chromatids

Answer 4

in dividing cells, each of the two identical parts make up a chromosome

Question 5

Centromere

Answer 5

holds the chromatids together until cell division occurs

Question 6

1. Interphase

Answer 6

time in which cell is performing its normal function, or it is preparing for cell division
– G1, S, G2

Question 7

G1

Answer 7

cells return to normal size after dividing, cells double the number of organelles they have, and gathers materials it needs for DNA synthesis

Question 8

S

Answer 8

a copy of all the DNA in the cell is made, and DNA is formed into chromosomes

Question 9

G2

Answer 9

synthesizes proteins needed for cell division to occur

Question 10

Cell Division

Answer 10

process by which cells replicate, creating two identical cells

Question 11

Mitosis

Answer 11

nuclear division in which genetic material is duplicated before the nucleus divides into two identical nuclei

Question 12

Cytokinesis

Answer 12

division of the cytoplasm of the cell

Question 13

G1 Checkpoint

Answer 13

checks to make sure that growth factors are present, DNA integrity is intact, and that the cell is duplicating its organelles
– if cell fails checkpoint, it will move into G0

Question 14

G2 Checkpoint

Answer 14

checks to make sure that the DNA has actually replicated

Question 15

M Checkpoint

Answer 15

• between metaphase and anaphase
• makes sure that the chromosomes are properly attached to the spindle and will be equally distributed to each daughter cell
