GENIE DNA sequencing

This activity is a group-work tutorial where students explore the dideoxy (Sanger) DNA sequencing technique by acting as the Taq polymerase in a sequencing reaction.

Adults doing sequencing tutorial

This activity has been designed to follow the GENIE DNA structure tutorial, but can be carried out as a stand-alone tutorial if the students are already familiar with the molecular structure of DNA.

This session is suitable for students aged 16 and over, and all seem to really enjoy working out the solution in groups.

What this activity will demonstrate is:

  • How the process of dideoxy DNA sequencing works
  • How complementary base pairing is applied during sequencing reactions
