Is it true that both the promoter and terminator sequences are copied into RNA?

The correct response is based on the understanding of transcription, the process by which RNA is synthesized from a DNA template. In eukaryotic cells, transcription involves the binding of RNA polymerase to a specific region of DNA known as the promoter. This region is instrumental in initiating the transcription process, but it is not included in the final RNA product.

During transcription, RNA polymerase unwinds the DNA and synthesizes a complementary RNA strand from the template strand of DNA. The RNA is synthesized from the start site determined by the promoter and continues until it reaches the terminator sequence. However, while the terminator plays a crucial role in signaling the end of transcription, the sequences of both the promoter and the terminator are not actually transcribed into the RNA. The RNA transcript contains only the coding regions, which may include exons and potentially some adjacent intronic sequences if alternate splicing occurs.

Thus, stating that both promoter and terminator sequences are copied into RNA is incorrect, making the assertion that only the part of DNA that codes for the RNA is transcribed true. Therefore, the answer indicating that this statement is false is indeed accurate.
