Q1 · Biotechnology and its Applications (Class 12) · EASY
Bt cotton is a transgenic crop resistant to insect pests. The gene encoding the insecticidal protein is derived from which organism?
Q2 · Biotechnology and its Applications (Class 12) · MEDIUM
Human insulin produced by recombinant DNA technology uses genetically modified bacteria. The two chains of insulin (A and B) are produced separately and then combined. Which enzyme is used to join these two chains after removal of C-peptide?
Q3 · Biotechnology and its Applications (Class 12) · HARD
RNA interference (RNAi) is a method of gene silencing used in biotechnology and research. A nematode Meloidogyne incognita infects tobacco plant roots. Scientists developed a transgenic tobacco plant resistant to this nematode using RNAi. The transgenic plant produces dsRNA complementary to which target?
