1. Review Describe the three main difference between RNA and DNA
Explain List the three main types of RNA and explain what they do
Infer Why is it important for a single genes to be able to produce hundreds or thousands of RNA molecules

2. Ch 13 RNA and Protein Synthesis

3. RNA Nucleic acid that consists of a long chain of nucleotides
Copied from DNA.

4. Differences Between RNA and DNA
Sugar is ribose instead of deoxyribose
RNA is generally single-stranded and not double- stranded
RNA contains uracil (U) in place of thymine (T).

5. Comparing RNA and DNA
Roles of DNA and RNA are similar to the master plans and blueprints used by builders
Master plan has all the information needed to construct a building.

6. Never bring a valuable master plan to the building site, where it might be damaged or lost
Instead they bring inexpensive copies or blueprints.

7. Functions of RNA Disposable copy of a segment of DNA
Protein synthesis.

8. 3 Types of RNA
Messenger or mRNA
Ribosomal or rRNA
Transfer or tRNA.

9. Messenger RNA
Carry copies of DNA instructions.

10. Ribosomal RNA
Make up ribosomes.

11. Transfer RNA
Transfers each amino acid to the ribosome according to mRNA.

12. Transcription
Segments of DNA serve as templates to produce complementary RNA molecules
Makes a copy
Occurs in nucleus of eukaryotes.

13. RNA polymerase Enzyme similar to DNA polymerase
Binds to DNA and separate strands
Uses one strand of DNA as a template and makes a complementary RNA strand.

14. Promoters Regions of DNA that have specific base sequences
Shows RNA polymerase where to bind and start
Similar signal shows where to stop.

15. RNA Editing Exon Intron
The part of the DNA that codes for the protein that is to be made
Intron
The part of the DNA that does NOT code for the protein that is to be made.

16. Why Have Introns Genes and Protein instructions may overlap in DNA
Instructions for one protein may cut out one set of introns, but different introns may be cut out for a different protein
Don’t have a complete answer
Neapolitan ice cream.

17. Chocolate
Exon
Vanilla
Intron
Strawberry
