DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

The sugar-phosphate chains form the backbone of the ladder-like DNA structure and these base pairs form the rungs. The width of each of these ‘rungs’ are the same as it involves one purine (A ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to ...

Water molecules surround the genetic material DNA in a very specific way. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have discovered that, on the one hand, the texture of this ...

Photo 51 was proof that DNA’s helical structure had two strands attached in the middle by the phosphate bases. They hurried to publish their findings in the journal Nature.

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

Considering a single strand of DNA or RNA, one end is designated as the 5′-end (five prime end), because in the chemical structure of the molecule it frequently has a phosphate group attached to ...

The sugar-phosphate backbone torsion angles also differ from those in canonical B-DNA at the exchanging strands, notably ε 6 = -73.6° (∼ 180° in B I-DNA), in agreement with earlier preditions 13.
