- Describe translation, building a protein from that message
Active recall
Quick check
Answer each question before opening the answer.
Name the two stages of protein synthesis.
Transcription (DNA copied into mRNA in the nucleus) and translation (mRNA read at a ribosome to build the protein).
What decides which protein is made?
The sequence of bases (codons) in the gene, which sets the order of amino acids.
