Question : Centrosome undergo duplication during (i) of (ii) and begin to move towards opposite poles of the cell during (iii) state of (iv).

Answer»

`{:("(i)","(ii)","(iii)"," (iv)"),("S phase","INTERPHASE","Prophase","Mitosis"):}`
`{:("(i)","(ii)","(iii)"," (iv)"),("S phase","Interphase","Anaphase","Mitosis"):}`
`{:("(i)","(ii)","(iii)"," (iv)"),("Prophase","Mitosis","Metaphase","Mitosis"):}`
`{:("(i)","(ii)","(iii)"," (iv)"),("Prophase","Mitosis","Anaphase","Mitosis"):}`

Solution :In animal cells, during the S phase of interphase, DNA replication BEGINS in the nucleus and the centriole DUPLICATES in the cytoplasm. These duplicated centrioles move TOWARDS opposite poles of the cell in prophase of mitosis.
