mitosis

Question 1

what are the four stages of mitosis?

Answer 1

prophase
metaphase
anaphase
telophase

Question 2

what occurs during prophase?

Answer 2

> chromosomes condense (become visible) and two chromatids are joined by a centromere
nuclear envelope and nucleolus disintegrates and spindle forms

Question 3

what occurs during metaphase?

Answer 3

> chromosomes line up along the equator of cell (attached by their centromeres to the spindle fibres)

Question 4

what occurs during anaphase?

Answer 4

> each chromatid splits at the centromere and the chromatids are pulled apart to opposite poles by spindle fibres

Question 5

what occurs during telophase?

Answer 5

> chromatids reach poles and nuclear envelope and nucleolus reforms
spindle fibres disintegrates and the cytoplasm divides

Question 6

what is the purpose of mitosis?

Answer 6

to produce identical daughter cells for growth and asexual reproduction
