Gel electrophoresis method used to separate the coloured dyes in food colouring by Shandchem on flickr

The last section of work before IB1 exams!  This is cool stuff.  It is the “newest” part of the course as it involves science that is very current.  Here are some of the questions we’ll attempt to answer:-

  • What are the techniques of PCR and gel electrophoresis and how do they work?
  • What is DNA profiling and how can it be used to determine paternity or in forensic investigations?
  • What is meant by “gene transfer” and how can it be performed?
  • What are some examples of genetically modified crops or animals?
  • What are the potential benefits and harmful effects of genetic modification?
  • What is a clone? How can we clone using differentiated animal cells?
  • What are the ethical considerations of therapeutic cloning in humans?

Take a look at these notes: Genetic Engineering And here is a FABULOUS blog post from Mr Taylor with TONS of resources – videos, slideshows, interactive links – you name it, it’s here.  USE THEM!
