MCQ on Translation in Eukaryotes




In eukaryotes, translation occurs in the cytoplasm following transcription. The mRNA, after processing, binds to ribosomes, where it is decoded by transfer RNA (tRNA) molecules to assemble amino acids into a polypeptide chain. This process requires initiation, elongation, and termination factors for protein synthesis. This is an MCQ on Translation in Eukaryotes (Protein Synthesis in Eukaryotes).
