Marine Biotechnology CSIR NET | PYQ Part 1

Marine Biotechnology CSIR NET previous year questions explained with answers — Part 1, for CSIR NET Life Sciences aspirants. This lecture solves marine biotechnology previous year questions asked in the BET (Biotechnology Eligibility Test) 2011 and 2012 papers. With DBT-BET now merged into CSIR-UGC NET Life Sciences, these questions are directly relevant for the December 2026 CSIR NET exam. Each question is explained with the correct answer, the logic behind it, why the other options are wrong, and comparison tables for confusing terms — the revision format toppers actually use. Part 1 topics: pleomorphism and SAR11 bacteria, lithogenous sediments, probiotics in aquaculture, byssus threads and DOPA, Riftia chemosynthesis at hydrothermal vents, DMS and climate, Prochlorococcus, saxitoxin and paralytic shellfish poisoning, coral bleaching, tetrodotoxin, beta-glucan immunostimulants, Crab-Yon fibre, halocins, snow algae, Mytilus edulis as antifouling model organism, Pyrolobus fumarii, thraustochytrids, integrated multi-trophic aquaculture, carbon sequestration, ballast water, WSSV shrimp virus, domoic acid and shellfish poisoning, chitosan in medicine, Slocum gliders, biofouler Bugula neritina, microbially induced corrosion and foul-release coatings. Part 2 will cover the remaining 46 questions from BET 2013 to 2022. Comment 'PYQ' and I will share the practice PDF. Ideal for CSIR NET Life Sciences, GATE Biotechnology, BET and DBT-JRF aspirants.
