meiosis and mitosis

Question 1

steps in mitosis

Answer 1

interphase, prophase, pro metaphase, metaphase, anaphase, telophase, cytokinesis

Question 2

karyotype

Answer 2

stain chromosome arrays with fluorescent dyes to analyze them

Question 3

start and end cells in mitosis

Answer 3

Start: 4 sister chromatids, 2 homologous chromosomes, 1 homologous pair
End: 1 paternal and 1 maternal chromosome

Question 4

main objective of mitosis

Answer 4

cell division in which a mother cell divides to produce 2 genetically identical daughter cells
- does this by pulling sister chromatids to opposite polls and cell pinches off into 2

Question 5

steps in meiosis

Answer 5

same as mitosis, except 2 cycles

Question 6

main objective of meiosis

Answer 6

cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes
- does this by separating homologous chromosomes (paternal and maternal) in meiosis one and sister chromatids in meiosis 2

Question 7

which cycle in meiosis is similar to mitosis

Answer 7

meiosis II

Question 8

gametes

Answer 8

haploids, each have a single copy of chromosomes

Question 9

what initiates cell division

Answer 9

• packing into chromosomes
• doubling DNA
