If you made a change in the promoter sequence in the dna that inactivates the promoter, what would happen at the rna level?

If I made a change in the promoter sequence in the DNA that inactivates the promoter the RNA would not be made because the DNA helicase would not be able to recognize and bind the DNA.
A region of DNA that begins transcription of a particular gene is called a promoter in genetics.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
