Translation of mRNA in bacterial cells begins when A. An amino acid is added to the C-terminus of a polypeptide chain B. The initiator fMet-tRNA binds to a free 30S ribosomal subunit C. Peptidyl transferase catalyzes transpeptidation between adjacent amino acids D. The ribosome disengages from mRNA

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed. A. fungi B. prokaryotes C. eukaryotes D. protozoa and some plants

Which of the following keep the mRNA message from being broken down by enzymes in the cytoplasm?Group of answer choicesMethyl capExonsPromotersPoly-A tailIntrons

Select the antibiotic that inhibits the E. coli RNA polymerase, i.e. the transcription.Question 4AnswerA.rifampicinB.chloramphenicolC.none of theseD.penicillin

Which of the following events occurs during transcription?View Available Hint(s)for Part AThe message in mRNA is translated into a protein.Those segments of the RNA strand that do not actually code for the protein are removed.A molecule of RNA is formed based on the sequence of nucleotides in DNA.A cap is added to the RNA molecule.mRNA binds to a ribosome in the cytoplasm.
