Give one example to illustrate that transcription of eukaryotic genes is much more complicated than that of the prokaryotic 2.(20 Why many transcription factors contain DNA-binding domains? Is DNA binding domain alone can exert the activation or repression of the gene expression? Why?

3.(15Which classes of bacterial RNA need to be processed to become functional, and how? 4.(15)What is a ribozyme, list all the ribozymes that involve in RNa processing, and briefly describe their roles in the corresponding RNA processing events 5.(20) It is known that spliceosome carry out pre-mRNA splicing? Describe how the cis acting elements included in the pre-mRNA and the transacting factors included in the spliceosome interact with each other to accomplish the splicing event

6. One of the many surprises to come from the various genome projects is that the number of genes an organism has is not necessarily a good predictor of its complexity. For example, humans are clearly much more complex than nematode worms, yet only have about 50% more genes. How could splicing help resolve this paradox?(20 points)
