- 58. Summary First, the enzyme RNA polymerase comes in. It unwinds the double helix and adds the complementary nucleotides, there is also a complementary mRNA strand that forms. But, since it is RNA, the thymine is replaced with uracil. Then, the double helix closes back up after RNA polymerase goes through. The mRNA exits through the nuclear pores and travels through the cytoplasm to get to the ribosomes. Once in the ribosomes, the large and small subunit of the ribosomes bind with the mRNA. The ribosome begins at the start codon, that is always AUG. As the ribosome moves down the mRNA strand, the tRNA molecule, with the correct anti-codon sequence, then binds onto the codon. As the ribosome keeps on moving, the amino acids from the previous tRNA falls off and attaches to the next amino acid. This forms a peptide bond and the tRNA molecule falls off. This continues until the ribosome reaches the stop codon, the codon either has a sequence of UAA, UAG, or UGA. The polypeptide chain, that was formed from the amino acid, then folds into a three dimensional figure, also known as its tertiary structure.
