1 HKDSE BIOLOGY a modern approach List of clarification of the learning and assessment focuses of Biology Curriculum and relevant parts in the textbook The Curriculum Development Council and the Hong Kong Examinations and Assessment Authority released the Biology (S4-6) Curriculum Supplementary Document in November, The tables below are prepared basing on this Supplementary Document to indicate the relevant parts in the series HKDSE BIOLOGY a modern approach for teachers quick reference. COMPULSORY PART I. Cells and Molecules of Life Topics Clarification Relevant parts in textbook Molecules of life Biomolecules Movement of substances across membrane Diffusion, osmosis and active transport Cell cycle and division Stages of cell cycle Meiosis The following contents are not the learning and assessment focus: optical isomers, linear form of sugar molecules, structural differences of starch, glycogen and cellulose. Detailed mechanism of active transport is not the learning and Details of cell cycle are not the learning and Crossing over is a feature of meiosis. Book 1, Ch 2, p.31 Table 2.3 Book 1, Ch 5, p.131 The paragraph about first growth phase (G 1 ), synthesis phase (S) and second growth phase (G 2 ) Book 1, Ch Meiosis (Refer to the teaching notes on p.141.) Enzymes and enzymatic reactions Factors (temperature, ph, inhibitors) affecting the rate of enzymatic reactions Modes and mechanism of enzyme inhibition are not the learning and Book 1, Ch 6, p C.

3 Topics Clarification Relevant parts in textbook Applied genetics Recombinant DNA technology DNA fingerprinting Evolution Speciation isolation Detailed mechanism of recombinant DNA technology is not the learning and assessment focus. Recombinant DNA technology involves restriction and ligation. Detailed mechanism of DNA fingerprinting is not the learning and Details of different types of isolation are not the learning and Book 4, Ch 23, p A. Recombinant DNA technology (Refer to Teacher s Edition p.t13-15.) III. Organisms and Environment Essential life processes in plants Transpiration Process The explanation of transpiration pull should be linked with the sub-topic Movement of substances across membrane. Cohesiontension theory is not the learning and Transport of substances in plants Transport of water Translocation of organic nutrients Reproduction in humans Menstrual cycle Cohesion-tension theory is not the learning and Mass flow hypothesis of phloem transport is not the learning and Hormonal control of menstrual cycle is included in elective topic Human Physiology: Regulation and Control Aristo Educational Press Ltd. 3
