Unit 3-Molecular Genetics Lesson 5 13.0 Flashcards
1
Q
What must pre-mRNA undergo before it leaves the nucleus in eukaryotes?
A
Pre-mRNA must be processed to mRNA.
2
Q
What is added to the 5’ end of pre-mRNA during processing?
A
Guanine is added, forming the 5’ cap.
3
Q
What is formed by adding hundreds of adenines to the 3’ end of pre-mRNA?
A
The poly-A tail is formed.
4
Q
What happens to non-coding regions of RNA during mRNA processing?
A
Non-coding regions are spliced out.
