Question

multiple choice question
mutations in noncoding, regulatory sequences called
______ can produce changes in phenotype and
protein expression even though the gene for the
protein is not mutated.

homeotic genes
crispr tags
enhancers
telomeres

Explanation:

• Homeotic genes are involved in body plan development, not regulatory sequences for protein expression without gene mutation.
• CRISPR tags are related to gene editing technology, not regulatory sequences in the context of this question.
• Enhancers are non - coding regulatory sequences that can affect gene expression (and thus phenotype and protein expression) without mutating the protein - coding gene.
• Telomeres are repetitive sequences at the ends of chromosomes, not regulatory sequences for gene expression in this way.

Answer:

C. enhancers
