2. On the lines provided, identify each kindof RNA.

a. b c.

3. The master plan of a building shows how to build and place important parts of the building, such as walls, pipes, and electrical outlets. On the building site,workers use copies of the master plan called blueprints to show them what to do. The master plan is kept in the office. Explain how mRNA works like a blueprint in constructing proteins.RNA Synthesis
For Questions 4–10, complete each statement by writing the correct word or words.
4. The process of using DNA to produce complementary RNA molecules is called .
5. Thesequence of in mRNA complements the sequence in the DNA template.
6. In eukaryotes, RNA is formed in the and then travels to the .
7. The enzyme binds to DNA during transcription.
8. RNApolymerase binds to regions of DNA called , which are “start” signals for transcription.
9. are portions of RNA that are cut out and discarded.
10. are spliced together to make the final mRNA.13.2 Ribosomes and Protein Synthesis
