Is that true?
I know that cells in the brain have significant variability in DNA, but not really aware of what non-neuronal and non-brain cells in general typically have.
- arrosenberg 9mo agoEvery cell in your body (excepting red blood cells) has a complete copy of your genome. What differs is which portions are activated.
