WebThe RBS is transcribed as part of the mRNA, which means that it is synthesized by the RNA polymerase along with the rest of the mRNA. This sequence is located upstream of the start codon of the protein-coding region and is typically composed of a purine-rich sequence (AGGAGG) that base pairs with a complementary sequence on the 16S ribosomal RNA … WebFinal answer. Transcribed image text: Processing of the mRNA begins before transcription of eukaryotic mRNA's is complete. The end of the mRNA is prepared for recognition by the ribosomes of the cell and protected from exonuclease degradation by a process called "capping." During this multi-step process a nucleoside is added to the end of the ...
