Every cell in an animal's body carries the same DNA. Yet that single genetic blueprint somehow produces neurons that fire, muscles that contract, and tissues with entirely different jobs. How ...

One of the biggest quests in biology is understanding how every cell in an animal’s body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...

Learn how mapping gene-control switches in an ancient sea anemone reveals how identical DNA can produce many different cell types. Every cell in an animal’s body carries the same DNA. Yet that single ...
