replication

Question 1

during which part of interphase does DNA replication occur?

Answer 1

S phase

Question 2

what is the role of kinetochore microtubules in the cell cycle?

Answer 2

attaches to the centromere and maneuvers the chromosomes during mitosis

Question 3

what occurs during prophase?

Answer 3

chromatin condenses

centrioles move far apart and microtubules from cytoskeleton form spindle and aster

Question 4

what occurs during prometaphase?

Answer 4

spindle fibres in two populations; kinetochore and non-kinetochore
nuclear membrane breaks down

Question 5

What occurs during metaphase?

Answer 5

spindle is complete + aster expends to plasma membrane
centrosomes at opposite poles
kinetochore microtubules attached to chromosomes

Question 6

what occurs during anaphase?

Answer 6

kinetochores cleaved by separase enzymes
chromatids move to poles of cell
non-kinetochore microtubules pulled by kinesin, elongating cell

Question 7

How does cytokinesis occur?

Answer 7

ATP and myosin causes the contraction of actin myofilaments in the cortex
cleavage furrow forms
