Describe the sequence in bacterial mRNA that promotes recognition by the 30S subunit.

what is the difference between leader mRNA and attenuator sequence? Please explain the function of attenuator sequence in attentuation

Why does a bacterial mRNA bind specifically to the small ribosomal subunit?

Name the three major types of RNA s,specifying the function of each in the synthesis of polypeptide?

There are a number of conserved sequences found in an mRNA that dictate where splicing occurs. Where are these sequences found relative to the exon-intron junctions? What is the significance of these sequences in the splicing process? One of these important regions is the branch point A found in the intron. What is the role of the branch point A in the splicing process, and can this be accomplished with the OH group on either the 2′ or the 3′ carbon?

A synthetic mRNA added to a cell-free protein-synthesizing system produces a peptide with the following amino acid sequence: Met-ProIle-Ser-Ala. What would be the effect on translation if the following component were omitted from the cell-free protein-synthesizing system? What, if any, type of protein would be produced? Explain your reasoning. Q. Elongation factor Tu

Explain what is meant by the coupling of transcription and translation in bacteria. Does coupling occur in bacterial and/or eukaryotic cells? Explain.

Briefly, describe one mode of post-translational modification that occurs once translation is finished.

A synthetic mRNA added to a cell-free protein-synthesizing system produces a peptide with the following amino acid sequence: Met-ProIle-Ser-Ala. What would be the effect on translation if the following component were omitted from the cell-free protein-synthesizing system? What, if any, type of protein would be produced? Explain your reasoning. Q.Release factors RF-1, RF-2, and RF-3
