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.
