The correct mRNA secondary structure of transcriptional termination is __________ stem-loop structure.

Question

Quizplus · Accepted Answer

The transcriptional termination sequence in bacterial mRNA consists of a GC-rich hairpin (stem-loop) followed by a run of uracil (U) residues. This hairpin structure is formed by base pairing between complementary sequences in the mRNA. The stem is typically around 4 base pairs long and is formed by Watson-Crick base pairing between GC nucleotides. The loop can vary in size and sequence, but it generally contains a region of single-stranded RNA that is recognized by the termination factor rho or other factors to terminate transcription. The correct mRNA secondary structure of transcriptional termination is 3-4 stem-loop structure.
