Control, Cancer and Counting Through the Cycle

Name: Control, Cancer and Counting Through the Cycle
Author: StemPy Lab

What keeps the cell cycle in order, and what happens when it fails? You meet the checkpoints, the cyclins and the kinases they switch on, and the changes that lead to cancer. Then you do the sums of the topic: chromosomes, chromatids and DNA at every stage, DNA graphs, the mitotic index and the number of cells after many divisions. It serves the Indian syllabus (NCERT, NEET) and the matching topic of A-Level, IB and AP.

Lesson 1about 30 min
Checkpoints, cyclins and CDKs
A cell must not divide with damaged DNA or with half-copied chromosomes. Checkpoints stop it until all is well, and a pair of proteins, a cyclin and a CDK, switches each step on. This lesson names the checkpoints and the proteins that run them.

Lesson 2about 30 min
When control is lost: cancer
Cancer is cell division that has escaped from its controls. A cell that grows a tumour has usually collected several mistakes: accelerators that stay on and brakes that no longer work. This lesson shows what the mistakes are, how a tumour spreads, and why the treatments can harm healthy cells.

Lesson 3about 25 min
Counting through the cycle
NEET asks the same kind of counting question again and again: how many chromosomes, chromatids or units of DNA at a given stage, what a graph shows, how many cells after some divisions, how long a phase lasts. This lesson gives one method for each.
