Question

Centrosome undergo duplication during (i) of (ii) and begin to move towards opposite poles of the cell during (iii) state of (iv).
A. `{:(" (i)"," (ii)"," (iii)"," (iv)"),("S phase","Interphase","Prophase","Mitosis"):}`
B. `{:(" (i)"," (ii)"," (iii)"," (iv)"),("S phase","Interphase","Anaphase","Mitosis"):}`
C. `{:(" (i)"," (ii)"," (iii)"," (iv)"),("Prophase","Mitosis","Metaphase","Mitosis"):}`
D. `{:(" (i)"," (ii)"," (iii)"," (iv)"),("Prophase","Mitosis","Anaphase","Mitosis"):}`

Answer 1

Correct Answer - A
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.
