Answer:
The correct answer is separation of sister chromatids.
Explanation:
The metabolic phase of the cell cycle is called interphase. It comprises three stages, that is, G1, S, and G2. The main activity of interphase is to assist the cells in its growth and DNA replication, duplication of organelles, and thus, enhancing the cell's size.
In interphase, that is, post S phase, the chromosomes gets paired with each other and give rise to sister chromatids. They get combined with each other with the assistance of cohesin proteins. It is at the metaphase stage, that the cohesin protein gets dissociated apart and thus allows the sister chromatids to get separate from each other.
The event of the cell cycle that does not occur during some stages of interphase is the separation of SISTER CHROMATIDS.
The cell cycle is divided into the interphase and M (mitosis) phase.
The interphase is in turn divided into three stages: Growth 1 (G1) phase, Synthesis (S) phase, and Growth 2 (G2) phase.
The processes of duplication of organelles and increase in cell size occur during G1 and G2 phases.
The replication of the genetic material (DNA) occurs during the S phase.
The separation of sister chromatids occurs during the M phase (Anaphase).
In conclusion, the event of the cell cycle that does not occur during some stages of interphase is the separation of SISTER CHROMATIDS.
