Answer:
NUCLEIC ACIDS
Step-by-step explanation:
Four biomolecules are found in living systems and they are responsible for every process undergone by cells of living organisms. Nucleic acid is one of the four biomolecules, which is the precursor of another biomolecule called PROTEIN.
DNA and RNA are the two nucleic acids which contains segments called GENES that encodes the information needed for the synthesis of proteins and transfer of this information to offsprings. Genes found on nucleic acid biomolecules undergo expression to produce proteins. ENZYMES are proteinous molecules that catalyse biochemical reactions in living systems.
From the explanation above, this means that ENZYMES that catalyze reactions like breaking down amino acids are PROTEINS, which in turn are made from GENES carried by NUCLEIC ACID biomolecules.
Therefore, NUCLEIC ACIDS determine whether an individual inherits the inability to produce the enzyme needed to break down the amino acids
