QUESTION 0 In bacteria, transcription normally stops when __ ANSWER RNA polymerase reaches a stop codon on the mRNA RNA polymerase is denatured RNA polymerase reaches a termination signal on the DNA that leads to the formation of a hairpin loap in the mRNA mRNA reaches a specific length and detaches from the DNA molecule IDON'T KNOWYET

## Step 1<br />In bacteria, transcription is the process of creating an RNA copy of a sequence of DNA. This process is carried out by an enzyme called RNA polymerase.<br /><br />## Step 2<br />Transcription stops when the RNA polymerase reaches a termination signal on the DNA. This is different from the process of translation in eukaryotes, where transcription stops when a stop codon is reached on the mRNA.<br /><br />## Step 3<br />The stop codon is a signal for the termination of translation, not transcription. Therefore, the option "RNA polymerase reaches a stop codon on the mRNA" is not correct.<br /><br />## Step 4<br />The option "RNA polymerase is denatured" is also not correct. Denaturation of RNA polymerase would disrupt its function, but it is not a normal mechanism for stopping transcription.<br /><br />## Step 5<br />The option "RNA polymerase reaches a termination signal on the DNA that leads to the formation of a hairpin loop in the mRNA" is correct. The termination signal on the DNA triggers the formation of a hairpin loop in the mRNA, which signals the end of transcription.<br /><br />## Step 6<br />The option "mRNA reaches a specific length and detaches from the DNA molecule" is not correct. The length of the mRNA does not determine when transcription stops.
