______________________
- The drawings A-E show stages of mitosis in an plant cell.
(a) Which of the drawings A -E shows
(i) interphase ________ ( DNA is replicated)
(ii) prophase ________ ( chromosomes – 2 sister chromatids – shorten)
(iii) metaphase ________ ( sister chromatids line up)
(iv) anaphase ________ ( sister chromatids separate)
(v) telophase ________ (new nucleus forms at each end)
(vi) cytokinesis ________ (cell contents divided between 2 daughter cells )
(b) Give two processes which occur during interphase and which are necessary for nuclear division to take place.
