2、ry material 1、It had to replicate so that copies could be transmitted from parents to offspring. 2、It had to encode information to guide the development, functioning, and behavior of cells and organisms. 3、It had to change to account for the differences that exist among individuals.Three milestones

3、in genetic history 1、The discovery of rules governing the inheritance of traits in organisms. 2、The identification of the hereditary material and the elucidation of its structure. 3、The analysis of the hereditary material in human beings and other organisms The discovery of rules governing the inher

4、itance of traits in organisms. The identification of the hereditary material and the elucidation of its structure.RNA：A, G, C, U.DNA：A, G, C, T. The analysis of the hereditary material. The paragon of all the sequencing programs is the Human Genome Project, a worldwide effort to determine the sequence of approximately 3 billion nucleotide pairs in human DNA.DNA replication and gene expression Semi conservative replication.DNA replication and gene expressionCentral dogmaMutationGenetics and evolutionLevels of genetic analysis Classical genetics Molecular genetics Popu
