1
New cards
What binds the start codon during initiation?
Initiator tRNA (Met or fMet)
2
New cards
Where does the initiator tRNA first bind on the ribosome?
P site
3
New cards
What happens at the A site?
Incoming aminoacyl-tRNA binds.
4
New cards
What catalyzes peptide bond formation?
rRNA (peptidyl transferase, 23S/28S)
5
New cards
What happens at the E site?
Empty tRNA exits the ribosome.
6
New cards
What recognizes stop codons?
Release factors
7
New cards
What is the Shine-Dalgarno sequence used for?
Prokaryotic initiation (ribosome binding)
8
New cards
How do eukaryotes initiate translation?
Ribosome scans from 5' cap to first AUG
9
New cards
What is rRNA's role in the ribosome?
It performs catalysis (ribozyme)
