Genetic modification and biotechnology
Understandings:
Gel electrophoresis is used to separate proteins or fragments of DNA according to size.
PCR can be used to amplify small amounts of DNA.
DNA profiling involves comparison of DNA.
Application: Use of DNA profiling in paternity and forensic investigations, use for criminal cases, paternity suits, relationships between species..

Electrophoresis : Skill: Analysis of examples of DNA profiles.
Use BOTH of these excellent simulations to see electrophoresis in action and how the results are used!
Clones are groups of genetically identical organisms, derived from a single original parent cell.
Many plant species and some animal species have natural methods of cloning.
Animals can be cloned at the embryo stage by breaking up the embryo into more than one group of cells.
Methods have been developed for cloning adult animals using differentiated cells.
Application: Production of cloned embryos produced by somatic-cell nuclear transfer.

Theory of knowledge:
The use of DNA for securing convictions in legal cases is well established, yet even universally accepted theories are overturned in the light of new evidence in science. What criteria are necessary for assessing the reliability of evidence?

Skill: Design of an experiment to assess one factor affecting the rooting of stem-cuttings.
Aim 6: The design of a rooting experiment should ideally lead to the experiment actually being carried out by students.
A plant species should be chosen for rooting experiments that forms roots readily in water or a solid medium.

What is the new CRISPR?
How does it work? What advantages does it give us? Are there limitations we should think about with the use of this technology? Try your knowledge out to see if you can correct the space aliens problems with gene therapy through viruses.
