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?

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 ...

(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.

DNA and RNA use the same five-carbon sugar, ribose, in their structure. The deoxy- means that on one side of the base pair, there's a place where another base pair can attach itself by way of a ...

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.

PARylation is integral to many key cellular functions, including signaling modulation and DNA repair. PARylation is reversible and is undone by PAR erasers such as poly ADP-ribose glycohydrolase (PARG ...

It is a polymeric molecule composed of nucleotides, each containing a ribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), uracil (U), guanine (G), or cytosine (C). RNA is ...
