The structure of RNA is a single-stranded molecule made up of basic units called nucleotides that contain a nitrogenous base, a five-carbon sugar and a phosphate group. Although there is only one strand of RNA, as oppose... More »

Nucleotides are made up of a phosphate group, a nitrogen base and a pentose sugar. These structural units serve as the fundamental building blocks of nucleic acids, such as deoxyribonucleic acid (DNA) and ribonucleic aci... More »

Nucleotides are made up of a phosphate group, a five-ring sugar and a nitrogenous base. Nucleic acids, such as deoxyribonucleic acid (DNA) and ribonucleic (RNA), contain repeating nucleotides. Nucleotides link together t... More »

Ribonucleic acid, known as RNA, is composed of a combination of four different nucleotides: adenine, uracil, guanine and cytosine. Each nucleotide primarily consists of a ribose sugar (five-carbon ring) and a phosphate g... More »

The five-carbon sugar found in RNA is ribose. Ribose is an important carbohydrate for generating energy in the cells of living organisms. More »

Both DNA and RNA are macromolecules that consist of long chains of nucleotides. Both contain the specific nucleotide bases adenine, guanine and cytosine, although the fourth base differs between DNA and RNA. Both molecul... More »
