（DNA and histone proteins are packaged into structures called chromosomes.）
麻省理工大学(MIT)遗传学的授课录像，主要讲述染色体、基因组及基因突变和蛋白质的表达。讲课没有字幕，不过教授的授课状态很好，很有感染力。下面是MIT生命科学主页上对本课程的简介：
This course discusses the principles of genetics with application to the study of biological function at the level of molecules, cells, and multicellular organisms, including humans. The topics include: structure and function of genes, chromosomes and genomes, biological variation resulting from recombination, mutation, and selection, population genetics, use of genetic methods to analyze protein function, gene regulation and inherited disease.
