Question

A scientist modified the structure of a promoter region of a gene. What could be its effect on transcription and translation?

A. RNA polymerase no longer binds to the DNA, so DNA will be directly translated into protein.

B. RNA polymerase will now bind to the coding region of the gene and carry out transcription.

C. RNA polymerase may not be able to bind to the DNA, so transcription will not occur

Answer 1

C. RNA polymerase may not be able to bind to the DNA, so transcription will not occur

promoter region is for RNA polymerase to bind but this region is not transcribed out by RNA polymerase. If change this part, the polymerase might not be able to bind.

A is incorrect because if RNA polymerase can't bind to DNA, then no transcription which means no translation.
B is incorrect because RNA polymerase can't bind to the coding region.

Hmm, correct me if i'm wrong...

Answer 2

No need to correct you ~ you are quite correct. :D
