Question

Question 14 of 15 0.5 Points Which is most likely true of the mRNA (below, deplcted in orange) from posltion 48-100? (Immediately following the sequence given In question 15) Shine-Dalgarno Sequence mRN (+): coding (sense) strand -l: template (anti-sense) strand Promoter -40 -20 +1 50 100 O A. This region is unlikely to be translated due to the upstream stop codon O B. It is likely a splice variant, encoding for a longer protein O C. The region probably contains another gene with its own promoter O D. This portion may encode another protein within the same operon, for coupled transcriptionvtranslation O E. None of the above

Explanation / Answer

Option D. This portion may encode another protein within the same operon, for coupled transcription/translation.

Reason:

Shine-Dalgarno (SD) sequence is found in bacterial mRNA sequence. It is the binding site for ribosomes.

Operons are found in bacteria. Its a cluster of gene which are closed linked and transcribed under a single promotor.
