mitosis

Question 1

G1(cell growth)

Answer 1

AKA: 1st gap

normal everday cells

Question 2

G2

Answer 2

AKA: 2nd gap

microtubules/centioles (in centresome)

what cell needs to do mitosis

Question 3

S (DNA synthesis)

Answer 3

replicates DNA (chromosomes makes copy of themselves)

Question 4

prophase

Answer 4

• chromosomes condense(DNA)
• Nuclear membrabe disspears(breaks down)
• centisomes move to opp. sides of cell
• spindle starts to form

Question 5

metaphase

Answer 5

• longest stage of mitosis
• chromosomes line up on equational plate
• centrosome at one spindle pole

Question 6

Kinetochore

Answer 6

• protein that connects spindle fiber to chromosomes
• in centomere region

Question 7

all the DNA constitutes the cells _____

Answer 7

genome

Question 8

DNA molecules are packaged into __________

Answer 8

chromosomes

Question 9

to count chromosomes, count____

Answer 9

centromere

Question 10

Phases of cell cycle

Answer 10

Mititotic phase (M) (10%) (mitosis and cytokinesis)

Interphase (90%- cell growth and copying of chromosomes)

• G1 (cell growth)
• G2 (mirotubules/centrioles)
• S (DNA synthesis)(chromosomes make copy’s of themselves)

Prophase

Metaphase

Anaphase

telophase

Cytokinesis

Question 11

Anaphase

Answer 11

• fastest stage
• chromosomes pulled to opposite sides
• chromatids seperate from each other at centromere
• go from having 2 chromatids chromosome to two 1 chromatid chromosome

* KINETECHORE walks chromosme back ro centromere region

Question 12

Telophase

Answer 12

• opposite of prophase
• cytoplasm divided into 2 cells(cytokinesis)

Question 13

Cytokinesis

Answer 13

• in animal cells, occurs by a cleavage, forming a cleavage furrow
• in plant cells, a cell plate forms
