i) Which statement about the biosynthesis of proteins is NOT correct? tRNA molecules function as carriers of the amino acids for protein biosynthesis. The growing peptide chain results from a nucleophilic addition-elimination reaction by an amino group at an ester group. A codon is a three-base sequence in mRNA that is specific for a particular amino acid. The biosynthesis of proteins is called transcription. ii) Which of the following does not occur during pyrosequencing? A 3'-OH attacks the α-phosphorus of...

b: Before neutralization the solution (is
acidic/is basic) and the (protonated amino group/deprotonated amino
group/protonated ester group) makes benzocaine soluble in the
aqueous solution. When the sodium carbonate is added, the (amino
group is deprotonated/amino group is protonated/ester group is
deprotonated) and the neutral benzocaine produced has a (low
solubility in water/high solubility in water/higher density than
water).
The local anesthetic, benzocaine, can be prepared by the direct esterification of p-aminobenzoic acid with ethanol, using sulfuric acid as the catalyst....
