Final answer:
The promoter region is involved in the initiation of transcription. It is a specific sequence of DNA nucleotides that triggers the start of transcription.
Step-by-step explanation:
The component involved in the initiation of transcription is the promoter region.
The promoter region is a specific sequence of DNA nucleotides that triggers the start of transcription. It is located at the beginning of a gene.
During the initiation stage of transcription, the RNA polymerase binds to the promoter region and unwinds the DNA double helix to form a transcription bubble, allowing for RNA synthesis to begin.
The component involved in the initiation of transcription is the promoter region. A promoter is a specific sequence of DNA nucleotides found at the beginning of a gene, and it serves as the binding site for transcription factors and RNA polymerase to start the transcription process. Transcription begins with the formation of an initiation complex at the promoter, followed by the unwinding of the DNA double helix to allow RNA synthesis—a process sometimes referred to as a transcription bubble. Thus, the correct answer to the question is (d) Promoter region.
