It controls a cascade of alternative RNA splicing decisions that finally result in female flies. WHY is splicing a feature of eucaryotes and not procaryotes?

Gene transcription is a process that transfers the genetic information into carriers such as mRNA and guides subsequent cellular metabolic activities. Interruption of gene transcription will result in catastrophic impacts and lead to cell death. Many of the transcription inhibitors have decent pharmacological effects against tumor growth and a number of anti-cancer drugs have been identified or developed to restrain transcription, among which amatoxins have been shown to exhibit high tumor inhibition potency
