Challenge Question 1


The scientific research tea m developed understanding of the role of Auxin Binding Protein 1 (ABP1) in auxin
action using two key biotechnologies:
Transgenic plants
Polymerase Chain Reaction
By creating a transgenic plant where a gene could be turned on or off, the scientific team worked out what that ABP1 gene did in the cell and therefore the plant.
(a) Explain how a transgenic plant is created and what
biotechnologies are required to do this.
(b) Describe what mechanism the team used to turn the gene on and off
(c) Explain how PCR technologies are used to measure whether the gene is turned on or off
(d) Why did they also need to make observations of the plant using microscopes and simple measurements of leaves and roots?
