Final answer:
mRNA, tRNA, and rRNA are all involved in the process of protein synthesis.
Step-by-step explanation:
In translation, the process of protein synthesis, all three types of RNA are involved. mRNA provides the instructions for protein synthesis, tRNA transfers specific amino acids to the developing protein strand, and rRNA is a major constituent of ribosomes that ensures the proper alignment of mRNA and ribosomes. The mRNA molecule is read in sets of three bases called codons, with each codon coding for a single amino acid. Ribosomal RNA (rRNA) has an enzymatic activity and catalyzes peptide bond formation between amino acids. Transfer RNA (tRNA) carries the correct amino acid to the protein synthesis.
