Beginning with the binding of TFIID and extending through the addition of the PolyA tail, please outline the entire process of transcription in eukaryotes. Be sure that you address the transcription factors, binding of RNA Polymerase, the modifications made to the mRNA as transcription is occurring, the CTD tail and the phosphorylation patterns and what significance those have, and alternative splicing.

Distinguish between inducible operons and repressible operons and explain how they work. Describe the three types of prokaryotic genetic recombination (conjugation, transformation, and transduction). Explain how recombination might interfere with the metabolic functions of operons, such as the lac operon or trp operon of E. coli.
