What happens during termination in the transcription process?

During termination in the transcription process, the mRNA strand detaches from the DNA template. This phase is critical as it signifies the end of the transcription process where RNA polymerase encounters a specific sequence in the DNA known as a terminator. This sequence signals that the synthesis of mRNA is complete, and as a result, RNA polymerase stops adding nucleotides to the growing mRNA strand.

Once the mRNA is fully synthesized, it is released from the DNA template. This detachment allows the DNA strands to reform their double helical structure, thereby protecting the genetic material. Furthermore, it's important to note that the assembling of amino acids occurs later during translation, not during transcription, which is why options relating to the synthesis of mRNA or the activity of ribosomes are not relevant to the termination phase of transcription.
