NEET Biology Question Papers: Overview

Biology is considered one of the easiest sections in the NEET exam:

• It includes questions from both Botany and Zoology.
• The syllabus covers topics from Class 11 and Class 12.
• Practising previous year NEET papers improves speed and accuracy.
• Biology questions are important for breaking ties in NEET results.
• Preparation should align with the latest NEET Biology syllabus.
• Regular practice ensures better readiness for the NEET exam.

NEET Question Paper Biology: Important Questions for NEET

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

Q. 1 The Correct sequence of phases in the cell cycle is:

Option 1: $\mathrm{M} \rightarrow \mathrm{G} 1 \rightarrow \mathrm{G} 2 \rightarrow \mathrm{~S}$
Option 2: $\mathrm{G} 1 \rightarrow \mathrm{G} 2 \rightarrow \mathrm{~S} \rightarrow \mathrm{M}$
Option 3: $\mathrm{S} \rightarrow \mathrm{G} 1 \rightarrow \mathrm{G} 2 \rightarrow \mathrm{M}$
Option 4: $\mathrm{G} 1 \rightarrow \mathrm{~S} \rightarrow \mathrm{G} 2 \rightarrow \mathrm{M}$
The correct answer is option 4) $\mathrm{G} 1 \rightarrow \mathrm{~S} \rightarrow \mathrm{G} 2 \rightarrow \mathrm{M}$

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 $\mathrm{G} 1 \rightarrow \mathrm{~S} \rightarrow \mathrm{G} 2 \rightarrow \mathrm{M}$

Q. 2 The fruit fly has 8 chromosomes $(2 n=8)$ in each cell. During the interphase of mitosis, if the number of chromosomes in the $G_1$${}_{\mathrm{}}$ phase is 8, what would be the number of chromosomes after the $\mathrm{\$S\$}$ phase?

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

Solution:

The correct option is (1).

During the $S$ phase, DNA replication occurs, but the number of chromosomes remains unchanged because chromosomes are counted based on the number of centromeres.

Given:

Number of chromosomes in the ${}_{\mathrm{}}$$G_1$ phase = 8
After the $S$ phase, DNA content doubles, but chromosome number remains the same

Therefore,

Number of chromosomes after the $\mathrm{\$S\$}$
phase = 8

Hence, the correct answer is Option 1 (8).

NEET Biology Total Questions Chapter-wise Weightage

Refer to the chapter-wise Biology question patterns from previous NEET papers:

• Understand the exam pattern more clearly through analysis.
• Identify topics with the highest number of questions.
• Prioritise NEET high-weightage chapters during preparation.
• Focus on important chapters to maximise scores.
• Check the chapter-wise Biology question count from the previous year papers.

NEET Biology Chapter-wise Questions from Botany

The table below shows the number of NEET questions from different Botany chapters in previous years. This division helps aspirants identify the most important chapters. Aspirants can use this data to distribute study time effectively. Knowing the NEET biology chapter-wise weightage supports strategic preparation. Students can give special focus to commonly asked concepts. Continuous practice and revision of high-weightage Botany topics can improve performance in the NEET Biology section.

NEET Biology: Chapter-wise Questions From Zoology

The following table indicates the number of questions asked from Zoology chapters in previous NEET exams. The analysis helps aspirants in recognising key topics and concentrating on high-weightage topics. Important concepts such as human physiology, reproduction, and evolution are frequently asked, and therefore, Zoology is an important part of NEET Biology preparation.
