4.3 Transcription Flashcards
1
Q
What is the first step of transcription?
A
INITIATION - Transcription factors bond to promoter starting transcription
2
Q
What is the second step of transcription?
A
ELONGATION - Transcription factors aren’t bonded anymore and 5 prime protective cap is added on
3
Q
What is the third step of transcription?
A
TERMINATION - Specific gene code stops process, then adenine tail is added to the mRNA
4
Q
What are the major differences between DNA and RNA?
A
double vs single stranded, ACGT vs ACGU, deoxyribose vs ribose sugar
5
Q
What does the Enhancer do?
A
The Enhancer aka the Silencer controls flow in the eukaryotic gene
6
Q
What does the Promoter do?
A
Starts the process at the TATA sequence
7
Q
What are Introns and Exons?
A
Introns get spliced out during transcription, Exons stay in
