摘要
It was recognized that a majority of the whole human genome is transcribed but only about 2% of genome actually encode all the proteins that were supposed, according to the central dogma, executing most of the biological functions of an organism. At an age proteins dominate, over 90% nonprotein coding regions were long regarded as trash, but nevertheless it was puzzling why god would allocate such a big portion of a genome to things without obvious meanings, and such curiosity has heightened when it was shown among various genome sequencing projects that the percentage of non-coding sequences is in almost strict correlation with the complexity of the organisms.
