Life Cycle of a Cell Mitosis: Equational Cell Division

BLUFF

PRIZE?

There are three stages under interphase namely: G1, S, and G2.

During prophase, DNA starts to condense to form chromosomes.

G2 is when the cell starts to duplicate cell structures such as organelles to prepare for DNA synthesis.

Anaphase happens when the chromosomes align at the middle area of the cytoplasm.

Cytokinesis refers to the process in which nuclear materials start to completely divide.

Translation can happen in S phase of cell cycle.

Transcription can happen in M phase of cell cycle.

There is at least one stage of mitosis wherein the cell becomes a haploid.
