A nucleoli disappear b the mitotic spindle forms c each duplicated chromosome appears as two identical sister chromatids d the chromosomes condense e the centrosomes move away from each other f the mitotic spindle breaks down 13.

During mitosis and meiosis prophase is the first phase of the division cycle after DNA replication in G and S phases. See the answer See the answer done loading. 3 A phase in meiosis in which homologous pairs are separated from each other.

During prophase the parent cell chromosomes which were duplicated during S phase condense and become thousands of times more compact than they were during interphase. The mitotic spindle breaks down. During prophase the structure condenses and the nuclear membrane starts to break down.

C Homologues come very close together. Select all that apply aChromosomes migrate to the opposite poles bnuclear envelope disappears cchromosomes condense dSpindle fibers grow from the centrioles eCentrioles are pushed apart. Correct option is D Prophase of meiosis I is long and complex.
