Which is incorrect? a. Gene expression refers to the molecular mechanism by which a gene expresses a phenotype by synthesizing a protein or an enzyme, which determines the character.
b. Gene concept cannot be studied by the operon model.
c. Operons are segments of genetic material which function as a regulated unit that can be switched on and switched off.
d. An operon consists of one to seven structural genes.
