The Evolutionary Significance of MicroRNAs

This chapter explores the evolutionary origins and critical role of microRNAs in the development of complex life forms, tracing their presence from unicellular organisms to mammals. It details the biochemical processes involved in their production and function, highlighting how microRNAs regulate gene expression and enhance organismal complexity. The discussion further underscores how microRNAs contribute to evolutionary processes by modulating protein production, providing a mechanism for increased genetic diversity without the need for new protein coding genes.
