Question

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

• 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 1

Answer: (D)

'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 division of cytoplasm into two cells occurs; 'd' is S-phase which is second stage of interphase during which DNA duplication takes place.
