Refer to the related link to see a chart of mRNA codons and their corresponding amino acids. 20. mRNA is read by the ribosome in the 5'_to_3_direction, with polypeptides being synthesized in the Amino to Carboxyl direction. 21. Of the 2 types of point mutations (substitutions, insertions/deletions), which is more likely to be harmful and why?
