Review Questions
... DNA, the recipe for making proteins, never leaves the nucleus (nucleoid region in bacteria). Yet all the protein-making machinery is located out in the cytoplasm. So how does the information get to the cytoplasm? DNA is transcribed into messenger RNA. 2. What is a transcript? A transcript is not a c ...
