What is a Checkpoint? The Cell Cycle Engine The cell cycle engine is a complex regulatory system that orchestrates the processes of cell growth and division in eukaryotic cells. This engine primarily consists of cyclin-dependent protein kinases (Cdks) and their regulatory subunits known as cyclins. These components play a pivotal role in controlling the progression … Read more
What is Cell Cycle? Definition of Cell Cycle The cell cycle is a series of sequential events that occur in a cell, leading to its growth, DNA replication, and division into two daughter cells. It consists of interphase, where the cell prepares for division, and the M phase, which includes mitosis and cytokinesis. This process … Read more
