Hey hush!
It involves the hydration of C-N that's amide bond.
One product is a -COOH.
Another is an -NH2.
Note:- C-N bond is broken so separate the molecule from here. R-COOH AND H2N-R.

The mRNA forms the polypeptide chain and the tRNA molecules bring forth the anti-codons required to make the polypeptide chain.
The tRNA A is CAU - it's complementry codon in mRNA will be GUA (aminoacid Valine is present in the formation of sickle cell)
The tRNA B is CUU - it's complementry codon in mRNA will be GAA (aminoacid glutamine is present in the formation of sickle cell)
The tRNA C is UGA - complementry codon in mRNA is ACU (thronine is also present in the formation of amino acid of sickle cell)
But the tRNA D is UGC and its codon in mRNA is ACG (therefore, this amino acid is 'not' present in the formation of sickle cell)
