Synthesis of mRNA is1 pointin the 5' to 3' direction with new nucleotides being added to the 5' end of the mRNA molecule.in the 3' to 5' direction with new nucleotides being added to the 5' end of the mRNA molecule.in the 5' to 3' direction with new nucleotides being added to the 3' end of the mRNA molecule.in the 3' to 5' direction with new nucleotides being added to the 3' end of the mRNA molecule.able to proceed either from the 5' to 3' or 3' to 5' direction.

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

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
