IB Biology HL D1.1.4 PCR & gel electrophoresis
Practise explaining PCR stages and interpreting gel electrophoresis results, including primer roles, fragment movement and DNA band patterns.
How this is tested
- explain how heating, cooling, primers and polymerase amplify a chosen DNA region
- interpret gel diagrams to determine fragment size from distance travelled
- predict how DNA charge and electrode position affect movement through a gel
