Cell Cycle Phases: A Detailed Exploration of Mitosis and Interphase
The cell cycle is a fundamental process that governs cell growth, replication, and division, ensuring the continuity of life in eukaryotic organisms. This article examines a detailed diagram of the cell cycle, focusing on its two major phases—mitosis and interphase, with interphase further divided into G1, S, and G2 phases. By understanding these stages, we uncover the intricate mechanisms that regulate cellular function and reproduction, essential for tissue maintenance and organismal development.

Control of the Cell Cycle: The Role of Cyclins and Kinases in Regulation
The cell cycle is a tightly regulated process that governs cell growth and division, orchestrated by key molecules like cyclins and cyclin-dependent kinases (CDKs). This article examines a detailed diagram of the control of the cell cycle, highlighting how these molecules ensure proper progression through each phase, from G1 to mitosis. By understanding these regulatory mechanisms, we gain insight into the molecular checkpoints that maintain cellular health and prevent uncontrolled division.

HPV-Induced Cervical Cancer Development: Cell Cycle Disruption and p53 Deactivation
Human Papillomavirus (HPV) infection plays a crucial role in cervical cancer development through its interference with cellular checkpoint mechanisms and tumor suppressor proteins. This process involves complex interactions between viral proteins and host cell regulatory systems, particularly the p53 pathway. Understanding these mechanisms is essential for healthcare providers in developing effective prevention and treatment strategies.
