A) Each mutant gene affected three enzymes.
B) Each mutant gene affected a pair of enzymes.
C) Each mutant gene affected only one enzyme.
D) Mutant genes had no effect on the enzymes produced by the cells.
E) Each mutant gene affected as many enzymes as were present in a particular metabolic pathway.

Metabolic Pathway

A series of chemical reactions in which the product of one reaction becomes the substrate of the next reaction.

Enzyme

Biological molecules that act as catalysts, speeding up chemical reactions in the body without being consumed in the process.

Mutant Gene

A gene that has undergone mutation, altering its original function, which can have various effects on an organism's phenotype.
