Practice questions

During translation, a ribosome begins at a start codon and reads an mRNA 5′→3′ in sets of three nucleotides. A student compares two mRNAs that are identical except at codon 4: mRNA 1 has 5′-AUG GCU UAC GAA CCG-3′, and mRNA 2 has 5′-AUG GCU UAC UAA CCG-3′. In this system, UAA is a stop codon recognized by a release factor rather than a tRNA. All other codons shown are sense codons that recruit tRNAs carrying amino acids. Which outcome is most likely for translation of mRNA 2 compared with mRNA 1?
