Question

There is a mutation in a promoter next to a gene such that rna polymerase can never bind. what steps must occur for the gene to be transcribed?

There are three principles to keep in mind when predicting the sequence of the mRNA produced by transcription of a particular DNA sequence.
The RNA polymerase reads the sequence of DNA bases from only one of the two strands of DNA: the template strand.The RNA polymerase reads the code from the template strand in the 3' to 5' direction and thus produces the mRNA strand in the 5' to 3' direction.In RNA, the base uracil (U) replaces the DNA base thymine (T). Thus the base-pairing rules in transcription are A→U, T→A, C→G, and G→C, where the first base is the coding base in the template strand of the DNA and the second base is the base that is added to the growing mRNA strand.
