Revise Edexcel GCSE Biology 3.2.5 Stages of protein synthesis with the question bank, lessons, revision guides, and flashcards.
Describe the stages of protein synthesis, including transcription and translation: a RNA polymerase binds to non-coding DNA located in front of a gene • b RNA polymerase produces a complementary mRNA strand from the coding DNA of the gene • c the attachment of the mRNA to the ribosome • d the coding by triplets of bases (codons) in the mRNA for specific amino acids • e the transfer of amino acids to the ribosome by tRNA • f the linking of amino acids to form polypeptides
