NEET Question Paper Biology: Important Questions for NEET 2026

Here are some NEET biology previous year questions to give an idea about the NEET 2026 exam level.

Q. 1 The Correct sequence of phases in the cell cycle is:
Option 1: M → G1 → G2 → S
Option 2: G1 → G2 → S → M
Option 3: S → G1 → G2 → M
Option 4: G1 → S → G2 → M

The correct answer is option 4) G1 → S → G2 → M

Solution:

Interphase -

Interphase represents the phase between two successive M-phases.

wherein

The interphase lasts more than 95% of the duration of the cell cycle, also called the resting phase.

The cell cycle is divided into two phases: interphase and M- M-phase. During interphase, the cell grows and makes a copy of its DNA. During the M phase, the cell separates its DNA into two sets and divides its cytoplasm forming two new cells. Interphase is divided into three subphases i.e. G1 phase, S phase, and G2 phase. Thus, the sequence of the phase of the cell cycle is G1 → S → G2→ M

Q. 2 The fruit fly has 8 chromosomes (2n) in each cell. During the interphase of Mitosis, if the number of chromosomes at G₁ phase is 8, what would be the number of chromosomes after S phase?

Option 1: 8
Option 2: 16
Option 3: 4
Option 4: 32

Solution:

The correct option is (a)

It will be the same as that of G1, hence the answer is 8.
