Biomolecules weightage in NEET-UG 2026 and JEE Main 2026
These shares are measured across many years of past papers, so they describe the long run rather than predicting any single paper.
| Paper | Share of Chemistry | Typical questions | Typical marks |
|---|---|---|---|
| NEET-UG 2026 chapter-wise weightage | 3.9% | 1.8 | 7.1 |
| JEE Main 2026 chapter-wise weightage | 3.9% | 1.0 | 3.9 |
Previous year questions from Biomolecules
Past-paper questions are the most trustworthy material in the bank, and assembly reaches for them first when it builds a Biomolecules test. They are not listed separately here, because a question's value is that you meet it under a clock rather than that you read it in a list.
A Biomolecules test draws from all 256 published questions in this chapter, past papers first. Sit one now and see the per-topic breakdown.
