Biotechnology: Principles and Processes — NEET/JEE Questions, Notes & Weightage
Class 12 Biotechnology NEET weightage: High 3,699 questions
Covers genetic engineering tools (restriction enzymes, vectors, plasmids), recombinant DNA technology steps, PCR, gel electrophoresis, and the construction of a genomic/cDNA library. Restriction enzyme nomenclature and the rDNA technology workflow are consistently tested.

Frequently asked questions
What tool-related facts does NEET ask about most?
Restriction enzyme nomenclature (e.g. why EcoRI is named that way) and the specific role of vectors like pBR322 in cloning are the most frequently tested factual points.
Is the full rDNA technology process asked as a sequence?
Yes — isolation of DNA, restriction digestion, ligation, transformation, and selection of recombinants is often tested as an ordered-sequence or matching question.
How important is PCR for NEET?
Moderately — knowing the three steps (denaturation, annealing, extension) and the role of primers and Taq polymerase is usually enough.
