Final answer:
Translation in eukaryotic cells happens in the cytoplasm, where mRNA synthesized in the nucleus is used by ribosomes to build proteins.
Step-by-step explanation:
Translation in a eukaryotic cell occurs in the cytoplasm. Specifically, it takes place on ribosomes, which can either be free-floating in the cytosol or attached to the rough endoplasmic reticulum. The process involves the synthesis of proteins based on the mRNA template that has been transcribed from DNA in the nucleus. After mRNA is synthesized, it is exported to the cytoplasm through nuclear pores. Once in the cytoplasm, ribosomes read the sequence of codons in the mRNA, and tRNA molecules bring the corresponding amino acids to the ribosome to construct the protein sequence. This underlines the separation of the processes of transcription (in the nucleus) and translation, with translation occurring outside the nucleus in the cytoplasm.
