Transposons can integrate into the promoters of genes, what is the most likely outcome of such an event?

a) frame shift
b) altered gene expression
c) amino acid substitution
d) point mutation
e) deamination

B) altered gene expression

Explanation:

Promoter is non-coding DNA sequence responsible for initiation of transcription, as a first and most import step in the regulation of gene expression. Usually changing of promoter nucleotide sequence can lead to loss of promoter function. Sometimes transposons can contain additional promotor sequence which can be regulated by group of different proteins.

As a consequence gene expression in altered.    

i think the answer is b.
