BIO 260 Chapter 3 Transcription


1. Flow of Info in the cell: DNA->RNA->Protein: Central Dogma of Biology


2. Transcription: the process of making RNA based off instructions from a DNA template




3. 1. a DNA template w/ promoter and transcription unit


2. ribonucleotides (A,C,G,U) aka rNTPs


3. RNA polymerase enzyme: Requirements of Transcription end transcription.


4. Transcription Unit: stretch of DNA that codes for RNA and the sequences that start and




5. Promoter: DNA seq. that RNA polymerase binds to for transcription. Comes before the transcription unit. Not

, 6. 1. RNA coding region


2. Terminator: Parts of the Transcription Unit:


7. RNA Coding Region: DNA sequence used to build the new RNA molecules; UTRs, Protein coding region,


introns, terminator.

8. Terminator: - The DNA region on the template strand signals the RNA polymerase to ter minate transcription.


-often included in RNA molecules

9. 1. Initiation


2. Elongation


3. Termination: Three main processes of transcription


10. Initiation: DNA region on template strand that signals to RNA polymerase to terminate transcription.


-often included in RNA molecule
-promoter has consensus sequences that are conserved for many coding regions (ex. TATA region; TCAKTY initiator
sequence)

11. Transcription Start Site (TSS): first base that is used to build the new RNA molecule. RNA polymerase
