How many GTP are required to extend a peptide on a tRNA.

How many GTP high energy bonds are required to extend a peptide on a tRNA in the P-site by three amino acids (ending up in the Psite again) ?

by three amino acids (ending up in the Psite again) ?

I am pretty sure the answer is 3. Meaning 1 GTP for each amino acid added in. Does this sound right? IF wrong can you get me in the right direction.

thank you

I would agree

Cis or trans? That's what matters.
