Biology textbooks may be due for a rewrite. For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double ...

The double helix, though, is not the only form in which DNA exists. For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted, four ...

Major Advance Made On DNA Structure Date: May 4, 2005 Source: Oregon State University Summary: Oregon State University researchers have made significant new advances in determining the structure ...

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 ...

Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick.Created by Rosalind Franklin using a technique called X-ray ...

The structure of DNA made visible Date: August 31, 2015 Source: ResearchSEA Summary: From 1952, DNA was sequenced, modified and extensively studied, but no technique was able to produce clear ...

Overall structure. The prim-pol domain has a mixed α/β fold that does not resemble any known DNA polymerase structure, thus defining a new DNA polymerase family ().The most prominent features of ...

The discovery of the structure of DNA transformed biology profoundly, catalysing the sequencing of the human genome and engendering a new view of biology as an information science. Two features of ...

DNA, or deoxyribonucleic acid, is fundamental to your growth, reproduction, and health. Read about its basic function and structures.
