mRNA, ribosome, tRNA and aminoacyl-tRNA syntheatases are needed for translation.
Step-by-step explanation:
In the translation process message is decoded into a polypeptide. Through interlinking of peptide bond amino acid covalently strung together. In this process each amino acid has a carboxyl and amino group.
Ribosome is catalysed for this reaction and generate the one water molecule. It is a complex macromolecule. It exists in the prokaryotes. Gene make the protein through the process of translation. In translation process mRNA is decoded and resultant protein is built.
