Final answer:
The ribosomal RNA (rRNA) helps mRNA's message be decoded and coordinates with transfer RNA (tRNA) during protein synthesis. It ensures the proper alignment of mRNA, tRNA, and the ribosome. During protein synthesis, the rRNA in the ribosome catalyzes peptide bond formation and ensures the correct reading of codons on the mRNA by the anticodons on tRNA.
Step-by-step explanation:
The ribosomal RNA (rRNA) helps mRNA's message be decoded and coordinates with transfer RNA (tRNA) during protein synthesis. It ensures the proper alignment of mRNA, tRNA, and the ribosome.
During protein synthesis, the mRNA carries the genetic instructions from the nucleus to the ribosomes in the cytoplasm. The rRNA in the ribosome ensures that the mRNA and tRNA are aligned correctly, allowing the codons on the mRNA to be read by the anticodons on tRNA. The rRNA also catalyzes the formation of peptide bonds between amino acids.
For example, if the mRNA has the codon 'AUG', a tRNA molecule with the complementary anticodon 'UAC' will bind to it. This tRNA brings the amino acid corresponding to the codon to the growing polypeptide chain.
