If Orangutan’s share 97% of their DNA with humans, how are we so radically different?

Question

What goes on in that 3% it DNA, and what similarities do we share in the 97%?

In: Biology

Answer 1

Just because the DNA is the same doesn’t mean it’s used the same way. Different organisms share much of the same genes, but genes can be activated at different times or different amounts of proteins can be made from those same genes.

For example, both movie adaptations of Dune are based on the same book, but they are quite different.
