Match different stages of cell cycle given in column I with their respective features in column II and select the correct option.

Given below are two statements:

Statement I: The stage between meiosis I and meiosis II is called interkinesis and is generally long living.

Statement II: In meiosis division number of chromosome in parent and progeny cells same so it is also called equational division.

Which of the following statements are true?

(i) Some cells in the adult animals do not appear to exhibit division.

(ii) Many cells of animals divide only occasionally.

(iii) These cells that do not divide further exit G₁-phase to enter an inactive stage called G₀.

(iv) Cells in quiescent stage remain metabolically active but no longer proliferate unless called on to do so.

(v) In animals, mitotic cell division is only seen in the diploid somatic cells.

(vi) Plants can show mitotic divisions in both haploid and diploid cells.

How many statements are true for telophase?

(i) Centromeres split and chromatids separate.

(ii) Chromatids move to opposite poles.

(iii) Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements.

(iv) Nuclear envelope assembles around the chromosome clusters.

(v) Nucleolus, golgi complex and ER reform.

(vi) The individual chromosomes can no longer be seen and chromatin material tends to collect in a mass in the two poles.
