1
New cards
5' Cap
A modified guanine nucleotide added to the 5' end of mRNA
2
New cards
Function of 5' Cap
Protects mRNA from degradation and helps it bind to ribosomes
3
New cards
Poly(A) Tail
A string of adenine nucleotides added to the 3' end of mRNA
4
New cards
Function of Poly(A) Tail
Increases stability of mRNA and enhances translation
5
New cards
Introns
Non-coding regions in pre-mRNA that are removed during splicing
6
New cards
Exons
Coding regions that remain in the mature mRNA
7
New cards
Spliceosome
A complex of snRNAs and proteins that removes introns from pre-mRNA
8
New cards
Alternative Splicing
Process where different combinations of exons produce different proteins from the same gene
9
New cards
RNA Editing
Post-transcriptional modification that alters RNA nucleotide sequences (insertion, deletion, or substitution)
10
New cards
rRNA Synthesis Location
Nucleolus
