PCR, gel electrophoresis, sequencing, DNA profiling and recombinant DNA

What this note covers

1. PCR selectively amplifies a defined DNA region
2. Gel electrophoresis separates DNA fragments by size
3. DNA sequencing determines nucleotide order
4. DNA profiles compare variable loci probabilistically
5. Recombinant DNA joins sequences from different sources
6. Integrate methods into a defensible investigation
