RNA-based evolution

<p>RNA-based evolution is a <a href="/facts/Theory/9vrNS1Rr">theory</a> that posits that <a href="/facts/RNA/HxPeNfNj">RNA</a> is not merely an intermediate between Watson and Crick model of the <a href="/facts/DNA/nB89Iauz">DNA</a> molecule and <a href="/facts/Proteins/Jxmagu3E">proteins</a>, but rather a far more dynamic and independent role-player in determining <a href="/facts/Phenotype/vxWXKGLj">phenotype</a>. By regulating the <a href="/facts/Transcription_(genetics)/bDgp9HDN">transcription</a> in DNA sequences, the stability of RNA, and the capability of <a href="/facts/Messenger_RNA/oUL6qxQn">messenger RNA</a> to be <a href="/facts/Translation_(biology)/JcPC1rth">translated</a>, RNA processing events allow for a diverse array of proteins to be synthesized from a single <a href="/facts/Gene/e1swwPY6">gene</a>.  Since RNA processing is heritable, it is subject to <a href="/facts/Natural_selection/JXTte6en">natural selection</a> suggested by Darwin and contributes to the <a href="/facts/Evolution/Hj0qAaBk">evolution</a> and diversity of most <a href="/facts/Eukaryotic/SkwyPLMA">eukaryotic</a> organisms.
