Answer:
The correct answer would be D) Ribosomes.
Ribosomes serve as the site of translation in prokaryotes as well as eukaryotes.
It produce proteins or polypeptide chains with the help of mRNA (messenger ribonucleic acid) and tRNA (transfer ribonucleic acid).
It gets attached or assembled near the start codon of the mRNA. mRNA provides the instruction from the DNA (deoxyribonucleic acid) to the ribosome in the form of codon sequence.
The codon sequence are then decoded with the help of tRNA which then adds specific amino acid to the growing polypeptide chain.
As soon as the ribosome reaches stop codon, it releases the mRNA and polypeptide chain.
The peptide chain then undergoes various post-translation changes to become a mature and functional protein.
