Mitosis

Question 1

Nucleus is bound by nuclear membrane. One or more nuclei present. Chromosomes are not distinguishable. Near nucleus are centrioles at right angles to each other

Answer 1

Interphase

Question 2

Centriole pairs move towards opposite poles. Double chromosomes become visible as long threads. Fibers extend outward from centrioles and form start shaped structures called asters

Answer 2

Early prophase

Question 3

Spindle fibers form an extend between poles. Two halves of each double chromosome are connected at a region called the centromere

Answer 3

Middle prophase

Question 4

Double chromosomes begin moving towards the equator. Nuclear membrane and nucleolus disappear

Answer 4

Late prophase

Question 5

Centromeres of double chromosomes are lined up at the equator. At the end of metaphase, the chromosome centromeres divide and the two chromatids of each double chromosome become separate, duplicate chromosomes

Answer 5

Metaphase

Question 6

Separate duplicate chromosomes begin to move apart

Answer 6

Early anaphase

Question 7

Duplicate chromosomes move apart to opposite sides

Answer 7

Late anaphase

Question 8

Spindles and asters disappear. Nuclear membrane begins to form around each daughter nucleus. New nucleoli appear. Furrow forms

Answer 8

Telophase

Question 9

Two new daughters cells form

Answer 9

Interphase
