Common mistakes
Failing to address all three distinct parts of the question adequately (importance, mission features, applications).
Providing generic S&T points instead of specific nanotechnology examples for its importance and applications.
Omitting or giving insufficient detail on the 'salient features of the Indian Government’s Mission on Nanoscience and Technology'.
Not explicitly linking the applications to India's 'development process' with relevant examples.
Difficulty: Medium — Requires specific knowledge of nanotechnology's principles, the details of India's Nano Mission, and its diverse applications across various sectors relevant to national development. It's not a generic S&T question.
