The given figure is a schematic break-up of the phases/stages of cell cycle. Select the correct option regarding it.

Options

A. a' represents karyokinesis which is the division of cytoplasm.
B. b' is telophase which is just reverse of prophase.
C. c' is the best phase to count total number of chromosomes in any species.
D. in 'd' stage, replication of DNA takes place on the template of the existing DNA.

Answer

D

Explanation

a' is karyokinesis which consists of four consequent stages, prophase, metaphase, anaphase and telophase 'b' is therefore anaphase 'c' is cytokinesis which follows karyokinesis. During which divison of cytoplsm into two cells occurs, 'd' is S-phase which is second stage of interphase during which DNA duplication takes place.
