How are lac operons regulated?

Naturally, Aldosterone and Vasopressin are hormones that can increase the GFR by reabsorbing sodium and water in the nephron (suppression of these hormones will deliver the opposite result). This will...

These are basically sequences that code for that regulate the expression of the operon. In , they are usually located slightly upstream of the operon. The is a good...

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

Lactose does not easily diffuse across the E. coli and must be actively transported into the cell by enzyme permease the enzymes galctosidase, permease and transacetylase are produced in...

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...

Each phase has checkpoints where the cell components are checked to see if they can precede. One checkpoint checks the dna for damage, another checks the proper duplication of the...

Abiotically, population size can be regulated through natural disasters like floods, tornadoes, etc or things that affect climate like rain and temperature. Biotically, population size can be regulated by...
