Explanation / Answer

Part A
Coding regions = Exons
Noncoding regions = Introns
Introns are removed by splicing
Genes encode information for building functional polypeptides or RNA molecules
Promoters are bound by transcription factors
Repressor proteins bind to silencer sequences

Part B
Absence of Promoter leads to loss of gene expression (transcription)

Part C
Mutations in exons result in loss of function of gene products.
