Twelve null alleles of an intron-less Neurospora gene are examined, and all the mutant sites are found to cluster in a region occupying the central third of the gene. What might be the explanation for this finding?

All the mutant sites are found to cluster in a region occupying the central third of the gene because the mutation might have occurred in the promoter region for that gene.
Explanation:
- A promoter region can be described as a region which is present upstream from a gene which has to be transcribed.
- The recognition of the promoter region by the RNA polymerase is important for a gene to be transcribed.
- If a mutation occurs in the promoter region, then the mutation will be reflected in the gene being transcribed.
- Hence, due to a mutation in the promoter region, all the mutant sites are found to cluster in a region occupying the central third of the gene.
