In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

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?

TNA, like DNA and RNA, has a sugar phosphate backbone that carries information as a sequence of four different bases (A,T,C and G for short). But instead of ribose (as in RNA) ...

RNA consists of a sequence of organic nucleobase molecules which are held together by a so-called backbone consisting of phosphate and sugar groups. Such a sequence can exist as a single strand or ...

RNA consists of a sequence of organic nucleobase molecules which are held together by a so-called backbone consisting of phosphate and sugar groups. Such a sequence can exist as a single strand or ...

A sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. Moreover, phosphate is a critical component of adenosine triphosphate (ATP), which transports ...

Ribose is a sugar and the backbone of RNA along with phosphate groups. Their existence implies that extraterrestrial sugars that fell to Earth may have contributed to the formation of RNA on the ...

We also note that the sugar-phosphate backbone of the target RNA spanning the 10′–13′ segment forms intermolecular hydrogen bonds with the Ago scaffold in the 12-nucleotide (Supplementary ...

A single RNA strand folded on itself with nucleobases (green) and a ribose-phosphate backbone (blue) WIKIMEDIA, VOSSMAN RNA consists of a phosphate backbone, sugar, and four bases (A, U, C, G), and ...

Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder. During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as ...
