Cyclin and CDK in cell cycle progression | How Cyclin CDK works?

Cyclin and CDK are like train conductors that help cells move from one stage to another during growth and division.

Imagine your cell is a train that needs to go through different stations, starting at the station, going through the tracks, and finally arriving at the end of the journey. To switch between these stations, the train needs conductors who know when it's time to move on. These conductors are cyclin and CDK, short for cyclin-dependent kinase.

Think of CDK as a conductor who is always ready to work but doesn’t know the schedule. That’s where cyclin comes in, it's like a helper who gives the conductor a signal when it's time to move on to the next station.

When cyclin joins with CDK, they become a team that can turn on new activities inside the cell, like preparing for division or copying DNA. This teamwork is what helps the cell progress through its journey, from growing to dividing into two new cells.

So every time the cell needs to move forward in its cycle, cyclin and CDK step up, just like train conductors making sure everything runs smoothly.
