Cell Cycle and Mitosis Concepts

The video tutorial explains the eukaryotic cell cycle, focusing on interphase and mitosis. Interphase, where cells spend most of their life, is divided into G1, S, and G2 phases. G1 involves cell growth, S phase is for DNA replication, and G2 prepares the cell for mitosis. The Restriction Point in G1 determines if a cell proceeds to mitosis or enters the Go phase. The tutorial also covers chromosome duplication and the synthesis of proteins necessary for mitosis.
