1. C. On a ribosome

Step-by-step explanation:

Translation:

• Translation is the final step in the central dogma of molecular biology that involves the decoding and translation of the codons on mRNA to amino acid sequence.
• The genetic code is a scheme of 64 triplet nitrogeneous base codons that code for 20 amino acids.
• A tRNA molecule reads this codon sequence with the help of complementary anticodons and helps transport an amino acid to the ribosome for addition to the growing polypeptide chain.
• Protein synthesis occurs in the rough endoplasmic reticulum (RER) in the cytoplasm.
