Which one is correct for ${\mathrm{G}}_0$ stage?
I. It is a quiescent stage.
II. In this phase cell cycle is stopped
III. ${\mathrm{G}}_0$ cells do not grow or proliferate but are metabolically active
IV. ${\mathrm{G}}_0$ cells can divide in response to some stimulus

Mark incorrect statements : - - - - incorrect statement
(A) Meiosis involves only a single cycle of DNA replication
(B) Four haploid cells are formed at the end of meiosis-I
(C) Meiosis occurs in diploid cells
(D) In yeast, cell cycle takes about 90 minutes.

The events shown below occur during different phases :

(A) Centromere splits, chromatids separate and move to opposite poles, Chromatids are now called chromosomes

(B) Chromosomes cluster at opposite poles, decondensation of chromosome reappearance of NM, GB, ER and nucleolus

(C) DNA replication

(D) Spindle fibre attach to kinetochores and chromosome are arranged at equatorial plate

(E) Condensation of chromosomal material

Which of the following correctly identifies each of the phase described?
