🧪 Science Experiments That Changed the World

Meselson and Stahl showed how DNA copies itself

They proved that DNA replication is semi-conservative each new strand contains one old and one new strand.

This explained how genetic information is passed accurately.

Example: like copying a page where half is original and half is newly written.

• Showed how DNA replicates

• Semi-conservative process

• Key to genetics

• Explained inheritance mechanism
