Question

Central Dogma. Gene expression involves many sequential chemical steps. It is important to keep track of the order of these steps in the overall process of gene expression. [Organize the chemical steps in eukaryotic gene expression. In the space beside each step (left), write a number (1 – 7) indicating when it occurs, from the first to the last step.] ___ mRNA leaves the nucleus and enters the cytoplasm. _ Introns are removed and exons are joined. _ TATA binding protein (TBP) binds to a promoter. _ The 40S ribosomal subunit scans for the start codon. _ A DNA bubble opens within RNA polymerase. _ The signal sequence is inserted into the ER membrane. ___ Vesicles fuse with the Golgi apparatus.
