AIIMS 2019 Botany Transcription MCQ Question

Option D is correct because it accurately identifies the sequence of events in the process of transcription, where (a) Termination refers to the end of RNA synthesis, (b) Elongation describes the addition of ribonucleotides to the growing RNA strand, and (c) Initiation marks the beginning of transcription when RNA polymerase binds to the promoter region of the DNA. Other options are incorrect as they misplace the order of these fundamental steps; for instance, option A incorrectly lists elongation before termination, which disrupts the logical flow of the transcription process. Understanding these stages is crucial for grasping how genetic information is transcribed from DNA to RNA.
