mitosis, meiosis

Question 1

the genetic materials of the cell in the form of long thin threads of DNA wrapped around histone proteins

Answer 1

chromatin fibers

Question 2

carry the genes of the organisms

Answer 2

chromosomes

Question 3

serves as an attachment of the spindle fibers where the chromosomes are pulled to opposite poles during cell division

Answer 3

kinetochore

Question 4

paired organelles found in the cytoplasm near the nucleus and become visible only to take part in cell division

Answer 4

centrioles

Question 5

formed from the microtubules which are miniature tubes supporting the cell and similar to the skeleton of the body

Answer 5

spindle fibers

Question 6

2 main stages of cell division

Answer 6

interphase & mitosis phase

Question 7

undergoes rapid growth where organelles are formed

Answer 7

gap 1

Question 8

non-dividing cells stay here

Answer 8

gap 1

Question 9

dna doubles in this phase

Answer 9

synthesis phase

Question 10

at the end of this stage, each chromosome is made up of 2 sister chromatics attached at centromere

Answer 10

synthesis

Question 11

preparations for cell division

Answer 11

gap 2

Question 12

assembly of proteins are here

Answer 12

gap 2

Question 13

cell division phase

Answer 13

mitosis

Question 14

what is the division of the nucleus called

Answer 14

karyokinesis

Question 15

what the division of the cytoplasm is called

Answer 15

cytokinesis

Question 16

results to 2 daughter cells

Answer 16

mitosis

Question 17

spindle fibers emerge from centrosomes & nuclear envelope breaks down. nucleolus also disappears

Answer 17

prophase

Question 18

what kind of cell

there is cleavage furrow that separates the daughter cells

Answer 18

animal cells

Question 19

what kind of cell

cell plate separates daughter cells

Answer 19

plant cells

Question 20

there are two identical daughter cells after this

Answer 20

cytokinesis

Question 21

are surveillance mechanisms that monitor the order, integrity, and fidelity of the major events of the cell cycle.

Answer 21

cell cycle checkpoitns

Question 22

ensures that cell is ready to undergo DNA synthesis or S phase

Answer 22

g1 checkpoint

Question 23

make sure that the cell is mature enough to undergo M phase

Answer 23

g2 checkpoint

Question 24

occurs during metaphase stage of cell division, sees to it that the cell is ready to complete cell division

Answer 24

m checkpoint

Question 25

results from the inability to control their normal growth mechanisms

Answer 25

cancer

Question 26

are proteins that signal the cell cycle checkpoints.

Answer 26

cyclins

Question 27

provides the necessary signal for the cell to start or stop mitosis

Answer 27

cyclins

Question 28

are enzymes that remove phosphate from ATP and attach it to another molecule.

Answer 28

kinases

Question 29

Through this removal and attachment of phosphates in different molecules involved in mitosis, cell cycle control is achieved.

Answer 29

kinases

Question 30

proteins chromatin fibers wrap around

Answer 30

histone proteins
