CAIE A Level Biology 9700 · Nucleic acids and protein synthesis
Gene expression involves transcription followed by translation. Outline the key differences between transcription and translation. In your answer, you should refer to the following: location in the cell, the template used, the product formed, and the roles of RNA polymerase, mRNA, tRNA, and ribosomes.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
