To actually visualize the double-helical structure of DNA, researchers require special ... To see chromosomes in this way, scientists must first use a chemical process that attaches the ...

The structure of DNA can also be described as a ladder. The chemical backbones of the ladder are made up of sugar and phosphate molecules that are connected by chemical bonds. The rungs of the ...

Deoxyribonucleic acid (DNA) is the information-carrying molecule found in all living organisms. In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like ...

(Getty Images) Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers ...

The applied physicist explains how the structure of 52,000-year-old genes hint at the biology of an extinct animal ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...

Scientists at Scripps Research have now captured the first detailed images of the DNA repair protein, Pol-theta, in action, ...
