Practice question
Question
In an experiment the structural genes lacZYAof lac operon were found to be constitutively expressed. The following explanations were given for the constitutive expression (P) absence of a functional repressor due to mutation in the repressor gene lacI (Q) mutation in the operator that can no longer bind the repressor (R) mutation in the lacAgene Which of the following is CORRECT
Explanation
Mendelian segregation analysis shows allele distribution and recombination generate phenotypic variation. Consequently Both P & Q emerges as the valid choice since it follows segregation and linkage principles, aligning with established principles in genetics literature.
