“Genetic, mutation and evolution ” part of the knowledge content is rich, the law is complicated, the ability to test a large number, as the core knowledge of high school biology, has been subject to college entrance examination proposition people of all ages. The main focus of the test sites: (1) DNA crude extraction and identification, DNA is the main genetic material, human genetic disease surveys and other classic experiments as the background, to test the basic theory, operation and design capabilities. (2) The basic function of DNA as a link, a comprehensive examination of DNA replication, gene expression and other knowledge. (3) Through the creation of special situations, examine genetic laws and various errors now
