Multiple Choice
The functioning of enhancers is an example of which type of genetic interaction?
A
Epistatic suppression between two structural genes
B
Codominance at a single genetic locus
C
Direct protein-protein interaction between transcription factors
D
Regulation of gene expression by non-coding DNA sequences
Verified step by step guidance1
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.
