Exactly 66 years ago, on April 25, 1953, Francis Crick and James Watson published their famous article that showed that the shape of DNA is a double helix. They weren’t able to see DNA directly - it’s ...

When we learn about human genetics in high school biology class, one of the most basic things we learn about is the DNA double helix, the twisting ladder-shaped structure that holds our genetic code.

Introduction Ever wondered how DNA, the genetic blueprint of a life-form, can encode and pass on the information on how to grow and maintain that life-form? Just like a cookbook contains a recipe for ...
