Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life.

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...

Science never ceases to amaze us, and one of the most mind-blowing facts about the human body is the sheer length of our DNA. If you unraveled all the DNA in your body and laid it out in a straight ...

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases.

Following is a transcript of the video. Manny: Commercial DNA tests have been a huge trend lately. They were some of the most popular holiday gifts last year. Which makes sense, there's so much ...

What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic ...

Using cutting-edge cryo-electron microscopy, scientists at the University of Leicester have captured the first detailed “molecular movie” showing DNA being unzipped at the atomic level. The movie ...
