Question

________ marks the end of a gene and causes transcription to stop. a stop codon rna ligase a terminator methionine

Answer 1

Answer
A stop codon is responsible for stopping the transcription process. So the correct answer is stop codon.

Answer 2

Answer: Terminator

Step-by-step explanation: Terminator is a sequence of nucleotides, which is present at the end of the gene and it gives signal to RNA polymerase to stop the transcription process.

Stop codon is present in mRNA, and it terminates translation. So Stop Codon is incorrect answer. RNA ligase is not an enzyme used in transcription. Methionine is the amino acid first added to the peptide chain and its part of translation, so it is not a right answer.
