The process in the cytoplasm in which the nucleotide sequence carried by mRNA is used to assemble amino acids into a protein.
When describing translation, connect the order of mRNA codons to the order of amino acids in the polypeptide.
Keep the locations clear: transcription occurs in the nucleus; translation occurs in the cytoplasm.

Protein synthesis has two main stages: transcription, which makes this copy, and translation, which uses the copy to assemble a protein.
