Verified step by step guidance

Understand that enhancers are DNA sequences that do not code for proteins but play a crucial role in regulating gene expression.

Recognize that enhancers function by interacting with transcription factors and other proteins to increase the transcription of specific genes, often from a distance.

Identify that this interaction is not an example of epistatic suppression, which involves one gene masking the effect of another gene at a different locus.

Note that codominance refers to the expression of two alleles at a single genetic locus, which is unrelated to enhancer function.

Conclude that the correct classification of enhancer function is 'Regulation of gene expression by non-coding DNA sequences,' as enhancers are non-coding elements that regulate transcription.
