Protein Synthesis Practice

Protein synthesis happens in two stages: transcription and translation. Transcription takes place in the nucleus and is when DNA is transcribed into mRNA. Translation takes place in the cytoplasm at a ribosome and is when the mRNA codon is matched with a tRNA anticodon carrying an amino acid.

You will need to transcribe and then translate each DNA strand. The DNA strand already exists, but you must figure out the mRNA codons, tRNA anticodons and the amino acids (words) that the DNA codes for. The first one has been set up for you. You will need to set up the remaining DNA strands in the same way. Your sentences should make sense. If they don't, you know you have made a mistake!
