the mitotic cell cycle

Question 1

roles of spindles during mitosis

Answer 1

arranging chromosomes at the equator of the cell during meta-phase
to push/pull chromosomes to opposite sides of the cell

Question 2

changes that occur during prophase

Answer 2

nuclear envelope dissapearance
formation of spindles
chromosomes become visible/chromatids are condensed
centrioles move to opposite poles

Question 3

role of centrometre

Answer 3

to hold chromatids together

Question 4

role of centrioles in animal cells

Answer 4

organizing/assembling of microtubules
formation of spindle fibres
during cell division

Question 5

features of metaphase

Answer 5

each centrosome reaches a pole
the chromosomes line up at the equator of the cell
absence of nucleus
spindles fibres are fully formed to which centrioles are attached
