Online Mendelian Inheritance in Man (OMIM) is a comprehensive, authoritative compendium of human genes and genetic phenotypes that is freely available and updated daily. The full-text, referenced overviews in OMIM contain information on all known mendelian disorders and over 15,000 genes. OMIM focuses on the relationship between phenotype and genotype. It is updated daily, and the entries contain copious links to other genetics resources.
Molecular Biology: Structure and Dynamics of Genomes and Proteomes illustrates the essential principles behind the transmission and expression of genetic information at the level of DNA, RNA, and proteins. This textbook emphasizes the experimental basis of discovery and the most recent advances in the field while presenting a structural, mechanistic understanding of molecular biology that is rigorous, yet concise. The text is written for advanced undergraduate or graduate-level courses in molecular biology.
