Study provides insight into cellular defenses against genetic mutation

...of deoxyribonucleic acids (DNA), they are put into practice by ribonucleic acids (RNA). Messenger RNA (mRNA), a modified copy of DNA, is transported to cellular factories called ribosomes that receive instructions for building proteins by "reading" mRNA templates.
