mitosis

Question 1

what happens in mitosis

Answer 1

division and distribution of the cells DNA to its two daughter cells

Question 2

what type of cells undergo mitosis

Answer 2

somatic cells

Question 3

what is karyokinesis

Answer 3

nuclear division

Question 4

what is cytokinesis

Answer 4

cell division

Question 5

what are the phases of mitosis

Answer 5

prophase, metaphase, anaphase, telophase, and cytokinesis

Question 6

what happens in prophase

Answer 6

• chromosomes condense
• centriole pairs separate and move towards the opposite poles of the cell
• spindle apparatus forms and nuclear membrane dissolves

Question 7

what happens in metaphase

Answer 7

• centriole pairs are at opposite poles of the cell
• fibers of spindle apparatus attach to each chromatid at the kinetochore
• spindle fibers align the chromosomes at center of the cell forming the metaphase plate

Question 8

what happens in anaphase

Answer 8

• centromeres split so each chromatid has its own centromere, allowing sister chromatids to separate
• sister chromatids are pulled to opposite poles of the cell by shortening of spindle fibers

Question 9

what are spindle fibers made of

Answer 9

microtubules

Question 10

what happens in telophase

Answer 10

• spindle apparatus disappears
• nuclear membrane forms around each set of newly formed chromosomes
• chromosomes uncoil

Question 11

what happens in cytokinesis in animal cells

Answer 11

• a cleavage furrow forms and cell membrane indents along the equator of the cell, eventually pinching the cell and separating the nuclei

Question 12

what happens in cytokinesis in plant cells

Answer 12

a cell plate forms between the 2 nuclei , splitting the plant cell in half
