Quick explanation

• This point belongs to Genetics, especially Key Stages in Protein Synthesis: Transcription and Translation.
• You need to be able to give a clear account of the stages of protein synthesis, covering 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.
• Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
