Protein Synthesis – Mnemonic
Protein synthesis occurs with the help of Ribosomes. They consist of 2 subunits :
In Eukaryotes: 40S + 60S → 80S (Even).
In Prokaryotes: 30S + 50S → 70S (Odd).
A Ribosome has 3 sites:
A site = incoming Aminoacyl-tRNA.
P site = growing Peptide chain.
E site = holds Empty tRNA as its Exits.
Messenger RNA acts as the template for protein synthesis.
Initiation codon on mRNA.
AUG → inAUGurates protein synthesis.
Termination codons on mRNA:
UAA → U Are Away.
UAG → U Are Gone.
UGA → U Go Away.
Amino acid attachment arm has a C C A sequence by the help of which it forms ester bond with amino acid.
C C A – Can Carry Amino acid.
