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 opposed to the two stranded double helix of DNA, it does not always follow a linear pattern.

An RNA strand can undergo significant intramolecular base pairing to take on a three-dimensional structure. There are three main types of RNA, all involved in protein synthesis. Messenger RNA (mRNA) serves as the intermediary between DNA and the synthesis of protein products during translation.

The chemical structure of RNA is very similar to that of DNA, but differs in three primary ways: . Unlike double-stranded DNA, RNA is a single-stranded molecule in many of its biological roles and consists of much shorter chains of nucleotides. However, a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA.

RNA: RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil. Learn about the structure, types, and functions of RNA.

RNA has a simpler structure and is needed in order for DNA to function. Also, RNA is found in prokaryotes, which are believed to precede eukaryotes. RNA on its own can act as a catalyst for certain chemical reactions. The real question is why DNA evolved, if RNA existed.

The components of RNA are somewhat similar to DNA with three major differences. the pyrimidine base uracil replaces thymine and ribose sugar replaces deoxyribose. RNA mostly forms single stranded structure.

DNA and RNA are nucleic acids, which means that they are polymer macromolecules, the monomeric constituents of which are called nucleotides. Nucleotides consist of three distinct portions: a pentose sugar, a phosphate group and a nitrogenous base, selected from among four choices. A pentose sugar is a sugar that includes a five-atom ring structure.

Structure. DNA and RNA are nucleic acids. Nucleic acids are long biological macromolecules that consist of smaller molecules called nucleotides.In DNA and RNA, these nucleotides contain four nucleobases — sometimes called nitrogenous bases or simply bases — two purine and pyrimidine bases each.
