10. Asexual reproduction (mitosis)

Question 1

what happens when to much mitosis occurs?

Answer 1

cancer will happen!!

Question 2

what are the 6 stages of mitosis in a eukaryote?

think of the process that occurs

Answer 2

1. interphase (initiation)
2. prophase (pro-before)
3. prometaphase (before middle phase)
4. metaphase (middle
5. anaphase (away)
6. telophase and cytokinesis (two)

Question 3

explain three points of what happens in interphase. think when it begins, what the chormosomes are like and what happens during interphase

Answer 3

begins when the cell is produced

chromosomes are uncondensed

DNA replications occurs during interphase

Question 4

what are the two major phases in mitosis? what do each of these phases do?

Answer 4

interphase: cells spend 90% of their life here. preparing for cell division
cytokenisis: where the cell itself divides (from the cytoplasm) into two daughter cells

Question 5

what are the three things that happen in prophase?

what dissapers and forms?

Answer 5

chromosomes condense

nucleoulus dissapears

mitotic spindles forms

Question 6

what are the three things that occur during prometaphase?

think: what dissaperas, what assembles and what attaches

Answer 6

nuclear envolope dissapers

kineochore assemble on chromotid

microtubules attach

Question 7

what is the process that occurs during metaphase?

Answer 7

choromosomes line up at the metaphase plate

Question 8

what is the process that occurs during anaphase?

Answer 8

chromotids seperate to opposite poles. chromotids are now chromosomes

Question 9

what happens during telephase? two things - what starts forming again?

Answer 9

the parental cell starts to split into two cells, nuclear envolope starts to reform

Question 10

what happens during cytokinesis?

Answer 10

the clevage furrow splits the parental cytoplasm into two identical daughter cells
