  Chapter 12 - Molecular Phylogenies and Evolution


How are DNA hybridization, specific genes, or ribosomal RNA genes used in phylogenetic studies? How can these methods imply a "degree" of divergence?



How is DNA sequenced or cloned? What are restriction enzymes and how are their products detected? How might these methods be used in medicine? What are transgenesis or gene therapy?

Molecular methods help biologists in many ways. This web site provides another view of basic molecular strategies and how they might be applied.
