This 46-slide Powerpoint presentation covers 'Topic 3.5 - Genetic Modification & Biotechnology' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into three sections:
A - Techniques & Profiling
B - Genetic Modification
C - Cloning
The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or
revision. Please see the preview file for an idea of the slide aesthetic and level of detail. Slides with related YouTube videos have also been included, which might help familiarize
students with the topics.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: Gel electrophoresis is used to separate proteins or fragments of DNA according to size.
U2: PCR can be used to amplify small amounts of DNA.
U3: DNA profiling involves comparison of DNA.
U4: Genetic modification is carried out by gene transfer between species.
U5: Clones are groups of genetically identical organisms, derived from a single original parent cell.
U6: Many plant species and some animal species have natural methods of cloning.
U7: Animals can be cloned at the embryo stage by breaking up the embryo into more than one group of cells.
U8: Methods have been developed for cloning adult animals using differentiated cells.
A1: Use of DNA profiling in paternity and forensic investigations.
A2: Gene transfer to bacteria using plasmids makes use of restriction endonucleases and DNA ligase.
A3: Assessment of the potential risks and benefits associated with genetic modification of crops.
A4: Production of cloned embryos produced by somatic-cell nuclear transfer.
S1: Design of an experiment to assess one factor affecting the rooting of stem-cuttings.
S2: Analysis of examples of DNA profiles.
S3: Analysis of data on risks to monarch butterflies of Bt crops.
