The process of translation involves decoding the mRNA molecule to produce a sequence of amino acids, which are the building blocks of proteins. During this process, a molecule called tRNA brings a specific amino acid to the ribosome, where it is matched to the corresponding codon on the mRNA. This process occurs in groups of three nucleotides, or nitrogen bases, at a time. As such, the molecule that reads the mRNA three bases at a time and helps to guide the correct amino acid to the ribosome is tRNA, making option D the correct answer.
