Genetic engineering

Visual learning

Materials needed


Different no. of colored strings


1x bacterial DNA


1x plasmid



Human Chromosome (depending on how many chromosome you want to
show). Remember to wrap the strings in some toilet rolls, representing the
histone wrapping


Bags or containers


Shapes and colors can vary


Size of the human cell can be bigger, compared to the bacteria


Scissors


Restriction enzymes


Glue


Ligases


Small beads/ BB pellets (used in air guns)


Represent bacterial cells replicating


Powerpoint slides to link the demo back to the teaching


Show cartoon representation of the whole process. This can easily be found
on the web


Process


Explain the whole process using a specific
example, like the production of insulin.


During the process, show the students how
the transfer of genetic material is done.


Stop and ask question to test their
understanding


Highlight the limitations in the demo and link
them back to the teaching slides


Tips


Use exagerrated movements, like the tearing
up of the cell and cutting the DNA


Ask students to repeat the whole process
