RNA notes
Learning objective: To understand how the ‘recipe' found on a molecule of DNA is used to build a
protein.
1. DNA provides the instructions for building which type of biological molecule?
2. Where is DNA located in a eukaryotic cell? Where is it located in a prokaryotic
cell?
3. Which cellular structures are the “machines” that build proteins? Where are they
located?
4. If DNA can’t leave the nucleus, how do you think the DNA instructions get to the
ribosomes in the cytoplasm?
To the right is a model which shows the flow of
information in eukaryotic cells
5. Use the figure to fill in the blank:
DNA → _________ → protein
