As you continue the translation process you will reach to the stop Codon. The stop codon brings in the release factor (a protein) that will cleave the polypeptide attached to the tRNA at the "P" site and that terminates translation: Glu Trp lle Large Ribosomal Subunit Cys His Small Ribosomal Subunit Translation of RNA into Proteins E L IRNA Ribosome Stop 5 H DAQN ALM. RNA Amino Ac Large Ribosomal Subunit Go ahead and repeat the translation process but for Transcription translation Sequence II. Once you have formed the polypeptide from Sequence II select which amino acid is in the C-terminus. Pro Small Ribosomal Subunit Translation of RNA into Proteins E ERNA 6644955-56- Stop Ribosome
