Question

Suppose a scientist identified two E. coli mutants, called huh1 and huh2. The mutants have constitutive expression of the nop operon, which includes the genes nop1 and nop2. One of the mutants is a point mutation in a DNA‑binding site, and the other mutant is a deletion of the gene that encodes the DNA‑binding protein. Which term describes the regulatory function of the DNA‑binding protein?

Answer 1

The term used would be "activator"

Step-by-step explanation:

Proteins also play a role in our DNA in regulating gene activity. There are proteins, known as regulatory proteins, that bind to DNA at specific locations near genes and can control and even alter its expression. In this way, the cell controls which genes, among the many that make up our genome, will be activated. This enables cells to differentiate according to their function by activating different genes, even though all cells are composed of the same DNA. So we have the neurons that make up the nervous system, the hepatocytes that make up the liver, and the myocytes in the muscles, for example.

Answer 2

Activator or Inducer

Step-by-step explanation:

An activator or inducer is a protein that binds to a DNA sequence inducing it's expression.
