Place the steps of eukaryotic transcription in order of occurrence. RNA polymerase II binds DNA promoter element. Processed mRNA leaves the nucleus Ribonudeotides align with complementary DNA nucleotides. Guanylyl transferase adds a guanine cap to the 5' end of the mRNA. RNA polymerase unwinds DNA. RNA polymerase is released from DNA. The mRNA is polyadenylated and spliced. RNA polymerase links triphosphate ribonucleotides together.
