The pre-mRNA transcript and protein made by several mutant genes were examined. The results are given below. Determine where in the gene a likely mutation lies: the promoter region, exon, intron, cap on mRNA, or ribosome binding site.
a. normal-length transcript, normal-length nonfunctional protein
b. normal-length transcript, no protein made
c. normal-length transcript, normal-length mRNA, short nonfunctional protein
d. normal-length transcript, longer mRNA, shorter nonfunctional protein
e. transcript never made
