Karissa Sanbonmatsu: The biology of gender, from DNA to the brain

The video explores the complexity of gender identity beyond chromosomes, debunking myths about brain size and gender differences. It delves into epigenetics, explaining how DNA can remember past events and influence gender identity. The speaker shares personal experiences as a transgender woman and discusses scientific discoveries about DNA knotting and development. The importance of social support and identity acceptance is emphasized, highlighting the shared sense of commonality among women.

• Women are always better at math than men.

• Some women have a mix of different chromosome types.

• All women have the same brain structure.

• Women have larger brains than men.

What scientific field is mentioned as studying how DNA activity can change without altering the sequence?

• Biochemistry

• Astrophysics

• Neuroscience

• Epigenetics

How does the speaker describe the rebuilding process of cellular components?

• As a static process
