New breakthrough in building blocks of life

Chinese scientists have announced their findings on the secondary structure of chromatin, the pattern by which the human body is formed. Cheng Yingqi reports.

On April 25, 1953, a seminal article was published in Nature magazine detailing the distinct double-helix structure of DNA, allowing humans to have a first look at how living organisms are developed from their genetic blueprint.

However, the double-helix structure of DNA seemed unlikely to be the whole story to explain the complexity of life.
