- Gel electrophoresis is used to separate molecules on the basis of their size.
- Smaller molecules travel farther than larger ones.
- Because DNA has a net negative charge, it travels through the gel when an electrical field is applied.
- PCR amplifies a specific section of a DNA molecule, producing billions of copies of each molecule in the original sample.
- Each cycle doubles the number of copies of the target DNA section.
- Mutant males are used in the first generation of cross 2.
- Mitochondria and chloroplasts have many copies of their genomes in each cell, so those genes will be much more abundant in the sample.
- DNA barcoding is less subjective than classical taxonomy.
