How does lactose get into an E. coli cell if the lac operon is turned "off" and the cell is not synthesizing lactose permease?

Kidney is not a reproductive organ, hence there is no germ cell or haploid cell in kidney. Cells in kidney are all diploid.

Cells have two mechanisms for increasing their responsiveness to a hormone Down regulation It is the result of a decreased concentration of the receptor, fewer receptors means a smaller response...

is an inducible system , it remains generally in off state , but in presence of Lactose it is switched on So Presence or absence of Lactose regulates operon...

The of E . coli is a cluster of three structural genes, encoding involved in lactose metabolism and the sites on the DNA involved in regulation of the operon. Normally...

In , i gene is called Regulatory gene. It produces Repressor which bind on the operator region and hence does not allow the movement of Rna polymerase ,

In switch on condition of gene A codes for transacetylase (an enzyme), which convert lactose into its active form i.e. allolactose.

The lac operon codes for required to transport lactose into the cell and to break it down. CAP enables to use alternative carbon sources such as lactose in the...

If the level of inducer lactose is low then the operator is again blocked by repressor so that the structural genes are repressed once again; to repress the synthesis...

Basic Definitions: = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere. Cell Wall = the rigid 'armor' of the...

Operons were found in eukaryotes in the 90´s. Although they are common in prokaryotes, operons can be detected in chordates for instance. If you are interested, I´d suggest you have...
