Transcription: the making of mRNA

Central Dogma of Biology Transcription Translation DNA RNA Proteins

“The Central Dogma” ribosome protein RNA nucleus RNA DNA cytoplasm “TRANSLATION” RNA nucleus RNA “TRANSCRIPTION” DNA cytoplasm

Transcription: the making of mRNA

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.

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

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

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

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

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….
