The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly states 'Francis Crick proposed the Central dogma in molecular biology, which states that the genetic information flows from DNA→RNA→Protein', which directly identifies C as Francis Crick and confirms the flow direction (DNA→RNA→Protein) that matches A=transcription and B=translation.

We did this for 1,565 questions.

Every one traced to the exact sentence in NCERT that answers it, including 90% of the 2026 paper. Sit a mock on the real NEET 2027 computer interface and every mark you drop comes back with its line attached.
