Describe the 4 combinations of active or inactive regulatory proteins that could be present at any time in the cell

The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.  

The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:

1. Active repressor, active activator,

2. Active repressor, inactive activator

3. Inactive repressor, active activator

4. Inactive repressor, inactive activator

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

every el niño cycle is different. every year.
