Line 1: Line 1:
Ribozyme is an [[RNA|RNA]] [[Molecule|molecules]] which possess a [[Catalysts|catalytic]] activity due to the tertiary structure that it forms&nbsp;<ref>Berg J., Tymoczko J., Stryer L. (2007) Biochemistry, 6th edition, New York: WH Freeman.</ref>. One of the examples of the ribozyme is the 23S [[RRNA|rRNA]] which is responsible for catalyzing the linkage of to adjacent [[Amino acid|amino acids]] by a [[Peptide bond|peptide bond]] during the process of [[Translation|translation]]&nbsp;<ref>Berg J., Tymoczko J., Stryer L. (2007) Biochemistry, 6th edition, New York: WH Freeman.</ref>. The ribozymes were first discovered by two American scientist: Thomas Cech and Sidney Altman in 1970s. 20 years later they won a Nobel Prize for "discovery of catalytic properties of RNA"&nbsp;<ref>Nobelprize.org "The Nobel Prize in Chemistry 1989". Available at: http://nobelprize.org/nobel_prizes/chemistry/laureates/1989/ (last accessed 5 Dec 2010)</ref>. Some ribozymes can be known to be '[[Self splicing|self splicing]]' as shown in an experiement performed by Thomas Cech in the 1980s. This property was seen to be present in the&nbsp;''Tetrahymena ''ribozyme which&nbsp;is able to&nbsp;form smaller RNA sections&nbsp;from an RNA strand.&nbsp;This conclusion was made as intron removal occured without there being any protein catalyst present. All forms of ribozymes are often used as evidence for the [[RNA world hypothesis|RNA world hypothesis]].<br>
