Reg Of Gene Expression Flashcards
1
Q
What does methylation do
A
Physically blocks binding site of TF
2
Q
What does eIF3 do
A
Prevents premature binding of ribosomal subunit
3
Q
What does EF1 do
A
Blocks the A site
4
Q
What does EF2 do
A
Attach to charged tRNA

Q
How is EF2 regulated
A
When phosphorylated, it is inactive
