RNA

Ribonucleic acid (RNA) is a nucleic acid consisting of a string of covalently-bound nucleotides. It is biochemically distinguished from DNA by the presence of an additional hydroxyl group, attached to each pentose ring. While RNA usually contains uracil instead of thymine, this is not always true, for example in transfer RNA. One of the main functions of RNA is to copy genetic information from DNA (via transcription) and then translate it into proteins (by translation).

Nucleic acid: A nucleic acid is a complex, high-molecular-weight biochemical macromolecule composed of nucleotide chains that convey genetic information. The most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids are found in all living cells and viruses....

String: Generally, string is a thin piece of fiber which is used to tie, bind, or hang other objects. String can be made from a variety of fibres. The term has more specific meanings within certain academic disciplines....

Nucleotide: A nucleotide is a monomer or the structural unit of nucleotide chains forming nucleic acids as RNA and DNA. A nucleotide consists of a heterocyclic nucleobase, a pentose sugar (ribose or deoxiribose), and a phosphate or polyphosphate group. Nucleotides also play important roles in cellular energy t...
