162. Where does transcription occur? Translation?
163. How does the above differ in bacteria?
164. How is RNA synthesis different from DNA synthesis
165. How do the 4 nucleotides specify 20 amino acids? Why wouldn’t it work any other
way?
166. How is the template strand for RNA synthesis chosen?
167. How do RNA polymerase differ from DNA polymerase? What doesn’t it need?
168. Follow this diagram, what are the steps of RNA synthesis?
a.
169. The primary transcript of RNA is modified before it exits the nucleus. The 5’ end
receives a 5’ cap and the 3’ end, a poly-A-tail. What are these modifications?
170. What are the functions of the modifications?
171. What is RNA splicing?
172. What are introns (UTR/ intervening sequences?
173. What are exons?
174. What is a spliceosome? What do they do?
175. What is alternative RNA splicing?
