Seeds as sources of DNA
- Germination of seeds (carob and guar)
- Extraction of DNA from fresh tissues
- PCR amplification of extracted DNA
- Electrophoretic analysis of amplification products
Notes:
On germinated seeds of the guar plant and carob tree, we have found two DNA regions that we called ìmarkersî because they exist in both plants but (as seen in the next slides) with specific differences in their sequences depending on the species.
