8.3 Study Guide Flashcards
1
Q
What is the enhancer?
A
2
Q
What are the exons?
A
Sequences present in mRNA.
3
Q
What are the Introns?
A
Pieces of RNA that will be spliced out and removed.
4
Q
What happens in the initiation?
A
The TF (transcription factor) binds to enhancement regions and attacks RNA pol to copy genes to mRNA.
5
Q
What happens in termination?
A
The termination sequence is recognized and cut. Poly A tail is added to RNA. The longer the tail=longer the mRNA is in the cytoplasm=more protein can be made.
6
Q
What happens during alternative splicing?
A
Pieces are spliced differently because of different RNA or combinations of exons.
7
Q
How are base pairing rules different with RNA than DNA?
A
Instead of A, RNA uses U.
8
Q
What happens in transcription?
A
DNA is replicated into RNA, which makes protein.
