- 23. First DNA transcription takes place in the nucleus of the cell. RNA polymerase binds to the start of a gene on the double helix and it unwinds the DNA into single strands. As it goes along it uses one of the single strands as a template and builds a complementary mRNA strand. RNA polymerase uses RNA instead of DNA. Therefore, thymine is replaced by uracil. The mRNA breaks off from the template strand and moves from the nucleus into the cytoplasm through a nuclear pore, translation begins and DNA returns to its original double-helix formation. Then mRNA comes into contact with the ribosomes which consist of two parts; a large subunit and a small subunit. Ribosomes read the mRNA sequence and convert it into an amino acid sequence. The ribosomes begin translation at the start codon AUG and in this case, stop at the stop codon UGA. tRNA molecules transfer the amino acid to the ribosome. tRNA contains an anticodon on one end and an amino acid on the other. The tRNA with a complementary anticodon temporarily binds onto the codon, then the ribosome reads the next codon and another tRNA with a complementary anticodon binds. A peptide bond joins the two amino acids, and as the ribosome continues down the mRNA strand the first tRNA falls off, leaving its amino acid. The ribosome continues down the strand until the stop codon is reached, where the last tRNA falls off, leaving a chain of amino acids, which will then fold upon itself to give it its function.
