In this PCR experiment, students make billions of copies of a small amount of DNA in only 90 minutes. They just need to mix template DNA and primers with PCR beads that contain all of the other components required to carry out a PCR reaction. Students see the increasing amounts of DNA for themselves, taking samples every few cycles and analysing them on a DNA gel.

• For 10 lab groups
• PCR 3 hours; electrophoresis 45 minutes

Also required: 5 to 50 µl adjustable micropipettes, tips, thermal cycler, electrophoresis gel tank and power supply.
