If a protein is coded for by a single gene and this protein has six clearly defined domains, which number of exons below is the gene likely to have?
A) 11
B) 5
C) 8
D) 12
E) 14

Question

Each domain in the protein is likely to be encoded by a separate exon. Therefore, the gene would require at least six exons to encode the six domains. However, additional exons may be present for regulatory regions or alternative splicing. Option C provides the closest number of exons to meet the minimum requirement.
