Lecture 12 Flashcards
(8 cards)
1
Q
Where is the promoter region in eukaryotes?
A
Upstream, 5’
2
Q
What are core promoter sequences?
A
Found on the promoter region and they bind proteins that facilitate transcription by bringing RNA polymerase to the right place
3
Q
What are regulatory promoter sequences?
A
Regulate whether or not the RNA polymerase will drive transcription
4
Q
What do RNA polymerase I and III transcribe?
A
Ribosomal RNAs, tRNAs and small nuclear RNAs
5
Q
What are motifs?
A
DNA sequences upstream that dictate which and when genes are transcribed
They bring RNA polymerase to the start of transcription and bind further transcription factors
6
Q
What is TATA binding protein?
A
A general transvription factor
Doesn’t cause transcription but allows it to occur
