Gene expression from the lac operon can be controlled in many ways, including a robust negative regulation strategy Select mutat

Mutation that reduces the affinity of the lactose repressor for lactose.
Explanation:
The operon model is operated in prokaryotes for the regulation of gene expression. The lac operon is active for the metabolism of the lactose and the genes that are associated with the metabolism.
The repressor molecule regulates the expression of the Lac operon. This repressor molecule binds with the DNA sequence tightly and blocks the transcription. The mutation that results in the decrease ability or affinity for the lactose might results in the continuous expression of the gene.
Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. ... It is because density in an intensive property of matter. So they are not considered properties.
Just like the ABO alleles, each biological parent donates one of their two alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).
