mRNA Processing Flashcards
1
Q
Where does mRNA Processing mainly occur?
A
Eukaryotes (intron rich)
2
Q
What are introns?
A
Non-coding regions of mRNA that are spliced out during mRNA processing
3
Q
What are exons?
A
Determine the sequence of amino acids in the protein during translation and contains coding regions of mRNA
4
Q
What is splicing?
A
The removal of introns from the mRNA transcript and joins the exons together
5
Q
What is alternative splicing?
A
Different combinations of exons are included in the mature mRNA transcript
6
Q
5’ cap
A
helps protect the mRNA from degradation and assists in ribosome binding for translation
7
Q
3’ poly- A tail
A
helps stabilize the mRNA and facilitates its export from the nucleus to the cytoplasm
