Answer 1

the peptide bond is the covalent bond between Carbon atom in the carboxyl group ( C in the COO-) and Nitrogen atom in the amino group (NH3+) of two different amino acids, here the tRNA in the left-hand side is attached to the growing polypeptide chain, there are 2 amino acids attached to that tRNA, tRNA which is directly linked to the tRNA is the last amino acid added, this amino acid is linked to the 3` OH of the adenine in the tRNA using its carbonyl carbon atom, so when the next amino acid is added the Nitrogen atom of amino group of the next amino acid forms covalent bond between this Carbonyl atom, so the atoms which will form the peptide bond are 1-carbonyl carbon atom and 5- N of amino group B) 1 and 5
