Edgar, a biochemist, claims to have found a new variety of a type of small biomolecule. Edgar notes that there are now 21 types
of this biomolecule instead of the old known 20. The molecule can also be combined with others in its class to produce a wide variety of proteins, some liquid and others solid. What type of biomolecule did Edgar find? A.
a nucleic acid
B.
a monosaccharide
C.
an amino acid
D.
a fatty acid
I think the correct answer would be an amino acid. Edgar surely had found a new type of amino acid. It is known that there are about 20 amino acids present. These are the monomer units for proteins. Amino acids are important substances for living organisms.
