What is true of eukaryotic mRNAs? * Choose one: They are translated after they are exported from the nucleus. They must always be folded into a complex three-dimensional shape before they can be translated They are translated by enzymes that ride on the phosphorylated tail of RNA polymerase II. They are processed only after being released by the polymerase. • They are transcribed and translated simultaneously.

Part A What are three observations that suggested eukaryotic RNA was an intermediate between DNA and protein? Select the three observations. O DNA plays the major role in replication, which allows for sustainable transfer of genetic information. O RNA is transported out of the nucleus and into the cytoplasm where protein translation occurs. Three types of RNA are found in the cell, and all of them are involved in protein synthesis. O DNA is found in the nucleus and protein...
