1. 5-3 NOTES: RNA AND CENTRAL DOGMA

2. Starter Questions What is the function of DNA?
Stores information for making proteins
Where are proteins made in the cell?
On the ribosomes in the cytoplasm
Can DNA leave the nucleus? No
Then how can the information for making proteins get to the ribosome?
RNA is made

3. Central Dogma

4. Vocabulary Terms
Chromosome : A rod shaped structure made of one strand of DNA and protein
Gene= segment of DNA on a chromosome that codes for hereditary trait (protein)
RNA (Ribonucleic Acid): an intermediate between DNA and proteins, made of nucleotides

6. Vocabulary Terms
Transcription: DNA acts as the template for RNA synthesis (Making RNA)
Translation: RNA directs the assembly of protein synthesis (making protein)

8. Central Dogma Framework for understanding the flow of information
Information flows in the following way:
DNA  RNA  Protein

9. Draw and Label

10. What differences do you notice between RNA and DNA?

11. RNA vs DNA RNA DNA Sugar = ribose Sugar = deoxyribose
Uses uracil instead of thymine
Single stranded
DNA
Sugar = deoxyribose
Use thymine instead of uracil
Double stranded

12. Double Bubble RNA vs. DNA

13. Types of RNA
Messenger RNA (mRNA): single strand of RNA that carries information from DNA to ribosome

14. Types of RNA
Ribosomal RNA (rRNA): RNA that is part of a ribosome

15. Types of RNA
Transfer RNA (tRNA): transfers amino acids to the ribosome to make a protein
