This template is intended for use on nucleic acid structure pages. To insert use: {{DNA RNA structure}}. On the primary, secondary, tertiary and quaternary structure pages, it displays alternative versions of the image with the relevant section highlighted. Alternatively, for the non-interactive image, use [[File:DNA RNA structure (full).png]]
Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself (non-coding RNA) or by forming a template for the production of proteins (messenger RNA). RNA and deoxyribonucleic acid (DNA) are nucleic acids.

A highly evolved [vague] RNA polymerase ribozyme was able to function as a reverse transcriptase, that is, it can synthesize a DNA copy using an RNA template. [36] Such an activity is considered [by whom?] to have been crucial for the transition from RNA to DNA genomes during the early history of life on earth. Reverse transcription capability ...
The primary structure of a biopolymer is the exact specification of its atomic composition and the chemical bonds connecting those atoms (including stereochemistry).For a typical unbranched, un-crosslinked biopolymer (such as a molecule of a typical intracellular protein, or of DNA or RNA), the primary structure is equivalent to specifying the sequence of its monomeric subunits, such as amino ...
Double-stranded RNA forms an A-type helical structure, unlike the common B-type conformation taken by double-stranded DNA molecules. The secondary structure of RNA consists of a single polynucleotide. Base pairing in RNA occurs when RNA folds between complementarity regions. Both single- and double-stranded regions are often found in RNA molecules.
The mRNA stem-loop structure forming at the ribosome binding site may control an initiation of translation. [4] [5] Stem-loop structures are also important in prokaryotic rho-independent transcription termination. The hairpin loop forms in an mRNA strand during transcription and causes the RNA polymerase to become dissociated from the DNA ...
Gene structure is the organisation of specialised sequence elements within a gene.Genes contain most of the information necessary for living cells to survive and reproduce. [1] [2] In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.
