In a new study, researchers have unveiled a surprising potential hero in the battle against hair loss: 2-deoxy-D-ribose, a simple sugar molecule that forms the backbone of DNA. Could this natural ...

Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded. Additionally ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA carries genetic information.

(Remember, DNA is almost always in a double-stranded helical form.) Furthermore, RNA contains ribose sugar molecules, which are slightly different than the deoxyribosemolecules found in DNA.

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

Mutations in the gene, however, can impair the DNA repair process and increase the risk of tumor formation. Cells have another protein called PARP1 [poly(ADP-ribose) polymerase 1] that flags ...
