Mechanism :
Mechanism Here we have the mRNA who is after getting base pairs from the DNA Untranslated region. Start Codon (AUG) The small ribosome sub-unit attaches to the mRNA through the help of IF1,2,3 and looks for the AUG start codon After it attaches the a tRNA with metionine attaches to the ribosome. Then the large sub-unit joins with the small This causes the reliease of the IF factors and the process of translation can begin
Slide 3:
E P A AUG UCU GAU GGC GAG UGA Now we will take a look at the process of elongation Here we have the ribosome unit These are the 3 different sites in the ribosome tRNA with methionine The joining of the tRNA to the P site is helped By GDP and eIF 2 Now we Have a second tRNA molecule With the other amino acid A peptide bond forms Between the amino acids and moves the amino acid from A to P This process continues to add amino acids to the peptide until The ribosome reaches a stop codon Once it has reached the stop codon release factors come in instead of another tRNA and release the polypeptide and separate the two parts of the ribosome
