CAIE A Level Biology 9700 · Nucleic acids and protein synthesis
A eukaryotic cell contains a gene that codes for a digestive enzyme. Outline the processes of transcription and translation of this gene, describing the roles of the template strand, RNA polymerase, mRNA splicing, ribosomes, and tRNA anticodons. Also outline how a deletion of a single base in the coding region of the gene would alter the resulting polypeptide.
7 marks, so the mark scheme is looking for about 7 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
