MCQ on Translation (Protein Synthesis)




Translation is the process by which cellular machinery converts the genetic information carried by mRNA into proteins. It occurs in the ribosomes and involves decoding the nucleotide sequence of mRNA into the corresponding sequence of amino acids, crucial for protein synthesis. This is an MCQ on Translation (Protein Synthesis) in Prokaryotes and Eukaryotes.
