Answer:
Ribosome
Explanation:
Ribosomes are mainly made up of ribosomal RNA and ribosomal proteins. Each has two subunits (30S and 60S or prokaryotes) and 40S and 60S in eukaryotes. The smaller unit usually reads the mRNA -with the message from the nucleus -on how to ‘manufacture’ the proteins. The larger subunit actually does the translation by bringing in t_RNAs that carry specific amino acids and then forming peptide bonds between amino acids and ultimately forming polypeptide chains.
