If you made a change in the promoter sequence in the dna that inactivates the promoter, what would happen at the rna level? the mutation of the dna would be carried through to the rna sequence. the dna helicase would not be able to recognize and bind the dna, so the rna would not be made. nothing, the rna would be made as usual. the rna polymerase would not be able to recognize and bind the dna, so no rna would be made.

Imagine that certain laws of physics could be ignored and you were able to travel vast distances in moments. now imagine that you traveled to an earth-like planet located light-years away that is known to support life. think about what you’ve learned in this unit and make an argument for what you think would be the dominant type of life form on this planet. consider whether a notochord is required for an organism to manipulate its environment and become a dominant creature.

What processes take place before the mature mrna exits the nucleus?
