Biotechnology and its Applications. After the principles chapter cloning, vectors, bioreactors , this one is the "what do we use it for" chapter and I'm drowning in examples: Bt cotton, RNAi, golden rice, insulin, gene t
Gametes, meiosis, polar bodies, polar nuclei, 2n, n, 3n. Two Class 12 chapters that blur into one in the exam hall.
Revising the Living World for the third or fourth time and I realise I only memorised the ladder instead of understanding it. NCERT says living organisms show a hierarchy: cellular organelles, cells, tissues, organs, org

My football season is on, so I'm doing this on the bus to the matches with a notebook on my knee, and I need something compact. The chapter lists a bunch of families Leguminosae/Fabaceae, Cruciferae, Malvaceae, Composita
