8.3 study guide Flashcards
1
Q
Transcription
A
making RNA from DNA code
2
Q
Central Dogma
A
DNA—RNA—–Protein
3
Q
Eukaryotic Gene
A
enhancer–promoter—-exons—introns-exons–introns
4
Q
enhancer
A
additional binding site for transcription factors
5
Q
promoter
A
start site of transcription
6
Q
exons
A
sequences that will be present in the mRNA
7
Q
introns
A
will be spliced out and removed
8
Q
Stage 1: Initiation
A
attract and prepare RNA polymerase to begin copying gene sequence into mRNA.
9
Q
Stage 2: Elongation
A
as RNA polymerase copies DNA, other proteins are recruited that splice out introns
10
Q
Stage 3: Termination
A
At the polyadenylation site, the termination sequence is recognized and cut
