Mendelian Genetics and Cell Processes

Mr. Anderson previews the genetics unit, covering key topics such as the structure and function of DNA, the central dogma of molecular biology, the cell cycle including mitosis and meiosis, Mendelian and advanced genetics, and gene regulation. The unit aims to provide a comprehensive understanding of how genetic information is stored, expressed, and passed on through generations.
