STEP 2 RNA Slicing Flashcards
1
Q
What is involved in RNA splicing
A
2 Exons
1 Intron
2
Q
What is the coding region
A
Exons
3
Q
What is the noncoding region
A
Introns
4
Q
What region is removed for the pre mature RNA
A
Introns
5
Q
What is alternative spicing
A
When you can use the same gene to make different things
6
Q
What is a Poly A tail
A
Many adenine bases
7
Q
What end is the poly A tail at
A
3 prime end
8
Q
What does the Poly A tail do
A
Protect the mRNA and gene from being degraded in the cytoplasm
9
Q
What is the 5 prime cap
A
A modified guanine
10
Q
What does the 5 prime cap do
A
1-protect the other end of a gene from being degraded
2-lead and recognize ribosomes
11
Q
After step 2 where does the mature RNA go
A
1- Move into cytoplasm
2- Go into ribosome
3- Translation begins
