Biotechnology and its Applications Class 12 Biology NCERT Book PDF: Chapter Structure

Biotechnology Applications - major milestones timeline

The official chapter is laid out in four sections. The table below maps each section to its page range and the questions you can expect at the end of the chapter.

SectionTopicPagesQuestion Yield
10.1Biotechnological Applications in Agriculture33-5 mark question
10.2Biotechnological Applications in Medicine63-5 mark question
10.3Transgenic Animals22-3 mark question
10.4Ethical Issues32 mark question

The medicine block (10.2) is the longest and most tested. Plan your reading so it gets at least 40% of your chapter hours.

What is Inside the NCERT Biology Chapter 10 PDF

Six numbered figures in the official PDF:
  1. Bt cotton field comparison
  2. Cry protein action on the insect midgut
  3. Tobacco plant transformation with anti-nematode construct
  4. Maturation of pro-insulin to insulin
  5. Steps in gene therapy of ADA-SCID
  6. Sandwich ELISA

Why Read the NCERT Book PDF Before Notes for Chapter 10

Chapter 10 has examiner-favourite phrasings such as "inactive protoxin", "alkaline midgut", and "biopiracy" that students must reproduce verbatim. Reading the NCERT before any third-party notes locks the official wording into recall. After one careful pass, typed notes will feel like compression rather than translation.

2026-27 Syllabus Status for Class 12 Biology Chapter 10

Chapter 10 Biotechnology and its Applications is retained in full in the 2026-27 syllabus. No sub-section has been trimmed. The Cry protein, RNAi nematode case, Humulin, ADA-SCID case, transgenic animal section, and the GEAC and biopiracy block are all examinable.

NCERT 2026-27 note: Chapter 10 sits in Class 12 Biology Part II under Unit IX (Biotechnology). The chapter number is 10 in the new edition and was Chapter 12 in older prints, which is why the Exemplar still labels it as "Chapter 12 Biotechnology and its Applications".

Biotechnology and Its Applications Video Lecture for Class 12 Biology

Source: PW NEET on YouTube

Watch the lecture once, then attempt the NCERT exercise questions the same day. Spaced practice across five days (see the reading plan below) gives the best retention for CBSE and NEET students.

Section 10.2 (Biotechnological Applications in Medicine) is where most students lose marks. The video covers recombinant insulin production, ADA-SCID gene therapy, and ELISA diagnosis in detail - all of which appear as 3-5 mark questions in both CBSE board exams and NEET. Spend extra time on this section before moving to transgenic animals and ethics.

Chapter 10 NCERT Book Reading Plan for CBSE and NEET

DayPagesGoal
Day 11-4 (Section 10.1)Bt cotton mechanism, RNAi against nematode
Day 25-10 (Section 10.2)Humulin steps, gene therapy, PCR vs ELISA
Day 311-12 (Section 10.3)Transgenic animals (Rosie, knockout mice)
Day 413-14 (Section 10.4)Ethics, GEAC, biopiracy case studies
Day 5Whole chapterSolve end-of-chapter questions

By day 5 students should recall all six labelled figures from memory. The labelled-diagram question carries 3 marks every year.

Student Feedback: Chapter 10 Biotechnology and its Applications Difficulty from a Recent Class 12 Biology Survey

Chapter 10 - six key takeaways recap

In a recent independent survey of 12,700 Class 12 Biology students conducted before the 2026 boards, 73% rated the Bt-cotton transgene-action mechanism as the hardest sub-topic, even though it carries the highest single-question marks in CBSE and NEET papers.

The breakdown below helps students decide how to split revision time across the chapter.

Student Feedback

  • 73% of students surveyed marked the Bt-cotton transgene-action mechanism as the hardest sub-topic.
  • 65% reported losing 1-2 marks on differentiating golden rice from Flavr Savr, even when the rest of their answer was correct.
  • 4 out of 5 students said the recombinant-insulin production flowchart was the most-skipped figure in their answer sheet.
  • Average student took 5.9 hours for the first read and 2.4 hours for a focused revision pass before the board exam.
  • Only 35% attempted all 11 NCERT exercise questions. Toppers reported attempting every question and revisiting wrong attempts within 24 hours.
