3.5 - Genetic modification and biotechnology
Assessment statements
DCS Topic Code | Statement | Guidance |
3.5.U1 | Gel electrophoresis is used to separate proteins or fragments of DNA according to size. | |
3.5.U2 | PCR can be used to amplify small amounts of DNA. | |
3.5.U3 | DNA profiling involves comparison of DNA. | |
3.5.U4 | Genetic modification is carried out by gene transfer between species. | |
3.5.U5 | Clones are groups of genetically identical organisms, derived from a single original parent cell. | |
3.5.U6 | Many plant species and some animal species have natural methods of cloning. | |
3.5.U7 | Animals can be cloned at the embryo stage by breaking up the embryo into more than one group of cells. | |
3.5.U8 | Methods have been developed for cloning adult animals using differentiated cells. | |
3.5.A1 | Use of DNA profiling in paternity and forensic investigations. | |
3.5.A2 | Gene transfer to bacteria using plasmids makes use of restriction endonucleases and DNA ligase. | |
3.5.A3 | Assessment of the potential risks and benefits associated with genetic modification of crops. | |
3.5.A4 | Production of cloned embryos produced by somatic-cell nuclear transfer. | Dolly can be used as an example of somatic-cell transfer. |
3.5.S1 | Design of an experiment to assess one factor affecting the rooting of stem-cuttings. | A plant species should be chosen for rooting experiments that forms roots readily in water or a solid medium. |
3.5.S2 | Analysis of examples of DNA profiles. | Students should be able to deduce whether or not a man could be the father of a child from the pattern of bands on a DNA profile. |
3.5.S3 | Analysis of data on risks to monarch butterflies of Bt crops. |
