This protein synthesis flip book illustrates the process of transcription and translation. It shows DNA being transcribed into mRNA by RNA polymerase in the nucleus. The mRNA is then transported to the cytoplasm where it passes through ribosomes. During this process, transfer RNA (tRNA) molecules match to the mRNA codons and add amino acids to form a polypeptide chain through peptide bonds. Eventually a full protein is synthesized from the mRNA instructions.
