1
Q
Transcription
A
Enzymes make mRNA to code for proteins
2
Q
RNA polymerase
A
Makes RNA (reads DNA from 3’-5’)
3
Q
mRNA
A
Carries DNA information to ribosomes
4
Q
tRNA
A
Carries amino acids to mRNA
5
Q
rRNA
A
Helps in protein assembly in ribosomes
6
Q
Poly-A tail
A
Increases stability and helps export from nucleus
7
Q
GTP cap
A
Protects transcription and helps attach mRNA to ribosomes
8

A
Parts of mRNA that don’t code for amino acids
9
Q
Exons
A
parts of mRNA that code for amino acids
10
Q
Alternative splicing
A
Removing introns and combining different combinations of exons to code for a polypeptide
