The end of a gene during transcription is marked by specific sequences known as terminators. These sequences signal RNA polymerase to stop synthesizing RNA and detach from the DNA template. In eukaryotes, additional processing, such as the addition of a poly-A tail, occurs after transcription termination to finalize the mRNA molecule.
RNA polymerase reaches the end of a gene.
At first during transcription, RNA polymerase binds the promoter region of a gene to be transcribed. The end product would be the synthesized mRNA.
The Gene body is defined as an entire gene from the transcription start site to the end of the transcript.
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene
Transcription is the second part of the Central Dogma of biology: DNA to RNA to Protein. At the end of transcription, there is an RNA copy of the DNA segment that has been spliced so that it only contains the coding sequences for the gene. That is then exported for translation. This segment, the direct project of transcription is messenger RNA or mRNA.
During gene expression, transcription occurs in the direction from the 5' to the 3' end of the DNA strand.

RNA polymerase reaches the end of a gene.
The terminator sequence marks the end of a gene during transcription, signaling the RNA polymerase to stop. The stop codon, on the other hand, signals the end of protein synthesis during translation, causing the ribosome to release the completed protein.
At first during transcription, RNA polymerase binds the promoter region of a gene to be transcribed. The end product would be the synthesized mRNA.
The Gene body is defined as an entire gene from the transcription start site to the end of the transcript.
Transcription is divided into three regions: the promoter, which signals the start of transcription; the coding region, where the gene sequence is transcribed into RNA; and the terminator, which signals the end of transcription. During transcription, RNA polymerase binds to the promoter region, unwinds the DNA, reads the coding region to synthesize RNA, and stops at the terminator region to release the newly formed RNA transcript.

The transcription process stops.mRNA detaches and moves to the ribosomesTranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
The promoter typically lies next to the 5' end of a gene on the DNA sequence. It is the region where RNA polymerase binds to initiate transcription of the gene.
RNA polymerase reaches the beginning of the gene
During transcription, the DNA strand is read by an enzyme called RNA polymerase. The RNA polymerase moves along the DNA strand and creates a complementary RNA strand by matching nucleotides. The process starts at the 3' end of the DNA strand and moves towards the 5' end, resulting in the production of an RNA molecule.
