HCB-910 Cell Cycle Regulation
Campus ASAB
Programs PG
Session Fall Semester 2016
Course Title Cell Cycle Regulation
Course Code HCB-910
Credit Hours 3-0
Pre-Requisutes
Course Objectives This course is intended to provide foundational information biology of cancer cell, cell division and cell cycle checkpoint. The main theme centers around cell cycle checkpoints with specific emphasis on the biochemistry and genetics of DNA damage signaling pathways, DNA damage checkpoints, mitotic checkpoints and their relevance to human cancer.
