What will happen if rna polymerase fails to attach to the promoter. During transcription what happens to the rna polymerase if a repressor protein attaches to the operator. Transcription will not begin. The rna polymerase would not be able to recognize and bind the. Rna polymerase could not recognize the promoter so transcription would not occur.

If the transcription factor cannot bind the rna pol cannot attach to begin transcription. It cannot attach to the promoter. The mutation of the dna would be carried through to the rna sequence. What will happen if rna polymerase fails to attach to the promoter.

Translation will begin early. It cannot attach to enzyme 1. What would happen if there were a mutation in the operator of the trp operon. This rna may encode a protein or can have a function in and of itself such as trna mrna or rrna promoters are located near the transcription start sites of genes upstream on the dna towards the 5 region of the sense strand.

Connection for ap courses. An mrna strand will be made before translation begins. If you made a change in the promoter sequence in the dna that inactivates the promoter what would happen at the rna level. Rna polymerase binds to dna double helix unwinds.

The cap protein couldn t bind therefore shutting off the genes c. Rna polymerase will unwind dna strands. Therefore the answer seems to be rna attaches to dna through a small protein called the factor sigma once the rna polymerase attaches itself to a chain sequence called a promoter. The operator is the portion of dna at the beginning of a gene where a transcription factor or repressor binds.

What happens when rna polymerase attaches to the promoter. Nothing the rna would be made as usual. It separates the dna strands at one end and synthesis a complementary rna strand on the other. The dna helicase would not be able to recognize and bind the dna so the rna would not be made.
