RNA knows it has reached the end of a gene through specific signals in the DNA sequence, such as terminator regions. In prokaryotes, these signals can be distinct sequences that prompt the RNA polymerase to detach from the DNA. In eukaryotes, termination often involves additional factors and specific sequences that lead to the cleavage of the RNA transcript. These mechanisms ensure that the RNA synthesis stops accurately at the right point, allowing for proper gene expression.

This warning is reached close to halftime again near the end of the game?
the five minute warning
When was the US navy biggest?
The US Navy reached it's maximum number of ships in 1945 at the end of World War 2
Is the world going to end Saturday?
The world is not going to end. who ever told you that the world is gonna end that's a lie. i know it was in the newsapaper this week, but only god know's when its gonna end and if it is be prepared but no its not going to end ok
Is Stephen know the end of the world?
no
What is last steps during transcription?
RNA polymerase reaches the end of a gene.
What steps happen lasts during transcription?
RNA polymerase reaches the end of a gene.
How does RNA polymerase know where to start transcribing a gene into mRNA?
The enzyme that synthesizes RNA (RNA polymerase) binds specific DNA sequencesthat typically lie before the gene being transcribed. When everything it needs to start synthesis is properly assembled (any cofactors, etc.), only then can it begin transcribing DNA into RNA.
What happens at end of transcription?
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.
What happens at the end of transcriptions?
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.
What marks the end of the gene during transcription?
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.
Does the promoter on a DNA sequence lie next to the 5' or 3' end?
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.
How does Transcription take place?

How does transcription go from 3 to 5 in the process of gene expression?
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.
What is the final step of transcription?
The final step of transcription is the termination of RNA synthesis, where the RNA polymerase enzyme reaches a specific termination sequence in the DNA template. This signals the end of the gene, prompting the RNA polymerase to detach from the DNA and release the newly synthesized RNA molecule. The RNA undergoes further processing, such as capping and polyadenylation, before it is ready for translation.
Describe the transcription process in terms of the three regions of the gene?
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.
What is the order of actions by rna polymerase?
Binds to DNA, makes mRNA from DNA, detaches
