When this DNA is collected and purified, the result is a whitish, sticky substance that is somewhat translucent. To actually visualize the double-helical structure of DNA, researchers require ...

Despite her contribution to the discovery of DNA's helical structure, Rosalind Franklin was not named a prize winner: She had died of cancer four years earlier, at the age of 37.

She suspected that all DNA was helical but did not want to announce ... This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.

All the proteins involved are helical and make use of helices ... Here we have presented the three-dimensional structure of BAF, a dimeric HTH DNA binding protein, with no significant sequence ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...

Nucleosomes are repetitive building blocks introduced in the monotonous linear structure of double-helical DNA. It has been ...
