Name: _______________________________________________ B2 Six Mark Questions Date: A Bertin Before you start to answer the questions, what key ideas do you need to know? What key words will you need to use? Use a yellow highlighter and highlight the COMMAND WORDS in the question. Use a pencil or a pen and circle the sections with INFORMATION. What is the question asking you to do? (describe/explain/compare/evaluate?) How are you going to answer the question? (paragraphs/diagrams with annotations/table?) Questions Q1. * Discuss the advantages and disadvantages of the use of GM organisms.

(paragraphs/diagrams with annotations/table?) Q5. Mutations can occur in genes. Mutations can cause genetic disorders in humans. Phenylketonuria (PKU) is a genetic disorder caused by a gene mutation. People with PKU produce an inactive enzyme. The normal base sequence and the mutated base sequence which can cause PKU are shown below. normal base sequence ............ C T C G G C C C T............ mutated base sequence ............ C T T G G C C C T............ (i) Describe how the changes that have occurred in the mutated base sequence produce an inactive enzyme. (2) .............................................................................................................................................. .............................................................................................................................................. .............................................................................................................................................. .............................................................................................................................................. *(ii) Explain how the mutated base sequence will result in an inactive enzyme being produced during protein synthesis.
