Variation enters a lineage
A germline mutation can appear throughout the body and pass between generations. A somatic mutation stays within descendants of the cell where it arose.
An interactive biology explainer
One mutation is not one destiny.
Trace how origin, gene function, tissue context, repair, surveillance, and accumulated changes can lead toward inherited variation, a quiet cellular change, or one of many cancer pathways.
Educational context model only. It does not calculate personal cancer risk, diagnose disease, or use clinical or live data.
“Not all mutations are harmful. So how do some mutations lead to cancer while others make us who we are?”
That question from MIT Open Learning frames this lab. The answer is not a single good-or-bad switch: the biological outcome depends on context and combinations.
Grounded in the supplied MIT Learn Beyond Biology Podcast post featuring @MITBiology’s Summer Morrill.
Inheritance lens: germline changes can become part of the variation shared across a whole body and, sometimes, across generations.
Change the context. Watch the pathway change.
Every factor is visible and exportable. The score organizes this teaching scenario; it is not a probability, prediction, or clinical scale.

A change that can help make us who we are
This germline regulatory change is modeled with functioning repair and surveillance. In this context, variation is the central story, not uncontrolled cell growth.

Cancer usually needs a combination, not a universal mutation.
Different tissues and gene functions create different routes. That is one reason cancer is a family of diseases rather than a single disease.
Keep the reasoning, not just the result.
