Question

Quizplus · Accepted Answer

Biochemical tests look at the observable characteristics of microorganisms, which falls under their phenotype. These tests generally exploit an organism's ability to utilize or produce specific chemicals, such as sugars or amino acids, and provide clues as to the identity of the microbe. The genotype (genetic makeup) of an organism is not directly tested by biochemical assays, although it may influence the organism's phenotype. Plasmids and lysogeny are both specific biological structures or processes and are not directly relevant to biochemical testing.
