Electrostatic effects are widely accepted as being highly important to specific protein–DNA interactions and to the enzymatic processing of DNA. Among the more important and structurally specific of ...
32 P-label is introduced by incoming dGT 32 P molecule. The arrows indicate the sites of enzymatic hydrolysis. The bases of the template DNA strand are designated as clear boxes, and the bases in the ...
DNA is made up of adenine-thymine (AT) bonds and guanine-cytosine (GC) bonds. The frequency of each type of bond differs substantially across bacterial species. A new study uses this quirk of ...
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 some ...
Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...
As imaging tools continue to get more sophisticated, researchers have been able to actually watch biological processes as they are happening in live cells. Scientists have now visualized loops of DNA ...
In Wikipedia, there are 21 scientists listed who made significant contributions to determining the structure of DNA. In recent decades the focus has been on the contributions of only 3 of those ...
Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...
On February 28, 1953, two scientists, James Watson and Francis Crick, announced they had figured out the structure of DNA. DNA or deoxyribonucleic acid, is the hereditary material in humans and almost ...
Researchers at Aarhus University report a proof-of-concept DNA needle inspired by bacteriophages that can deliver molecules ...
DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...
