Phases of Cell Cycle — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Phases of Cell Cycle.

Integrated questions on DNA content and chromosome number changes across multiple phases.

high

NEET often tests the ability to track changes in genetic material. A question might present a cell with a certain DNA content and chromosome number in G1 and ask for its state in G2, Anaphase, or a daughter cell. This requires a comprehensive understanding of S phase replication and anaphase centromere splitting. For example, 'If a cell has 20 chromosomes and 20 picograms of DNA in G1, what will be the chromosome number and DNA content in its anaphase?'

Conceptual questions on the significance or purpose of specific phases or events.

medium

Beyond just knowing 'what happens', NEET can ask 'why it happens'. For instance, the significance of the G2 checkpoint, the importance of metaphase alignment, or the role of the G0 phase in tissue homeostasis. These questions require a deeper understanding of the biological implications rather than just rote memorization of events.

Comparative analysis of mitotic events in plant vs. animal cells, especially cytokinesis and centriole involvement.

high

The distinct mechanisms of cytokinesis (cell plate vs. cleavage furrow) and the presence/absence of centrioles in higher plants are classic comparative points. Questions might present a scenario and ask to identify if it's an animal or plant cell division, or directly ask for the differences. This tests attention to detail and comparative biology skills.

Questions involving inhibitors of specific cell cycle phases.

low

While the detailed molecular regulation might be beyond NEET scope, basic questions about how certain drugs (e.g., colchicine affecting spindle formation) arrest the cell cycle at a particular stage could be asked. This links the phases to practical applications and experimental observations, requiring an understanding of what each phase entails.
