Transcription Flashcards
1
Q
Step 1
A
The RNA polymerase binds to the promoter region
2
Q
Step 2
A
This intiates transcription
3
Q
Step 3
A
RNA polymerase uncoils the DNA
4
Q
Step 4
A
Only the template strand is used
5
Q
Step 5
A
Free nucleoside triphosphates bind to their complementary bases on the template strand
6
Q
Step 6
A
Adenine binds to Uracil instead of Thymine
7
Q
Step 7
A
As the nucleoside triphosphate bind they become nucleotides and release energy losing two phosphate groups
8
Q
Step 8
A
The mRNA is built in a 5’-3’ direction
9
Q
Step 9
A
RNA polymerase forms covalent bonds between the nucleotides and keeps moving along the DNA until it reaches the terminator
10
Q
Step 10
A
The terminator signals the RNA polymerase to stop transcription
11
Q
Step 11
A
RNA polymerase is released and mRNA detaches from the DNA
12
Q
Step 12
A
DNA rewinds
