Explain the steps involved in the process of transcription, including the role of RNA polymerase, promoter and terminator sequences, and mRNA processing. Also, discuss the significance of transcription in regulating gene expression, including the types of regulatory elements that affect transcription, such as enhancers and repressors. Finally, explain how mutations in transcription factors or regulatory elements can lead to changes in gene expression and ultimately affect cell function.
