Initiation, elongation and termination Flashcards
1
Q
what does the initiation stage do?
A
brings together mRNA, a tRNA with first amino acid and 2 ribosomal subunits
2
Q
what happens in the elongation stage?
A
amino acids are added one by one to the preceding amino acid
3
Q
what are the steps of the addition of proteins aka elongation factors?
A
codon recognition, peptide bond formation and translocation
4
Q
when does termination occur?
A
when a stop codon in the mRNA reaches the A site of the ribosome
5
Q
what does the termination reaction release?
A
Polypeptide
