5. Transcription: the making of mRNA

6. Transcription: the making of mRNA
Helicase: an enzyme that unwinds DNA
RNA polymerase: an enzyme that binds to DNA to make RNA.
MessengerRNA(mRNA): carries code from DNA out into the cytoplasm.

7. Transcription: the making of mRNA
Helicase: an enzyme that unwinds DNA
RNA polymerase: an enzyme that binds to DNA to make RNA.

8. “The Central Dogma” 1) Transcription: making RNA Helicase unwinds DNA
RNA Polymerase makes mRNA

9. “The Central Dogma” 1) Transcription: making RNA
RNA Polymerase makes mRNA
mRNA then leaves nucleus

10. Draw and label the steps of transcription.
Draw Out Activity (Notebook):

Use the following words to draw and label the steps of transcription as well as identifying where it occurs. Hint: Three Steps
Helicase mRNA Cytoplasm
DNA Nucleus RNA polymerase

11. Closure: Please answer the following question in a complete sentence.
Why does RNA need to be made for DNA’s message to be read?
RNA needs to be made for DNA’s message to be read because….
