mitosis

Question 1

interphase of mitosis

Answer 1

aka G2, chromosomes duplicate but not necessarily condensed

Question 2

prophase of mitosis

Answer 2

chromosomes form/condense, nuclear envelope disappears as lamin proteins phosphorylated by MPF, mitotic spindle forms and attaches to kinetochores of duplicated chromosomes

Question 3

metaphase of mitosis

Answer 3

chromosomes align on metaphase plate in middle of cell - splitting sister chromatids down the middle - homologs DONT interact

Question 4

anaphase of mitosis

Answer 4

cohesin, which keeps sister chromatids together, is broken down, chromosomes separate as sisters pulled toward opposite poles by motor proteins

Question 5

telophase of mitosis

Answer 5

formation of 2 new identical daughter nuclei

Question 6

cytokinesis of mitosis

Answer 6

cell splits into equal halves - new cell plate forms or cleavage by constriction of actin filaments
