Answer
Option C is correct i.e " mRNA haipin followed by a poly-U-sequence".
Explanation
Prokaryotic (bacterial) transcription termination occurs either Rho dependent or independent mechanims. In Rho independent mechanisms transcription termination sequence forms within the mRNA itself i.e haipin forms followed by the poly U sequence.
Stop Codon is required for translation termination.

TranslationOverview:The purpose of this activity is to help the students to understand how replication, transcription, and translation are connected. Students will use a sequence from a bacterial gene that confers resistance to antibiotics (carbapenems). They will be asked to apply the knowledge obtained in the class lecture to (1) find the promoter in the sequence, (2) determine the amino acid sequence of a fragment of the polypeptide, (3) "reverse translate" a fragment of the polypeptide, and (4) identify mutations in...
