The CFTR gene is a eukaryotic gene, but how is the gene structured in terms of the numbers and lengths of exons and introns? "Sketch" a rough, but labelled diagram of the exon/intron structure of the CFTR gene and explain the significance of exons and introns and what such gene structures mean in terms of gene function. As part of the explanation, address the relationship between allelic variants and gene structure

    Genes in eukaryotes are often organized into exons and intrans, which require splicing to produce an mRNA that can be translated. The gene organization is the order of the DNA segments that comprise the gene starting with the promoter, the first exon, the first intron, the second exon, and so on. The interspersed intrans can make gene identification difficult in eukaryotesparticularly in higher eukaryotes with many introns and alternative spliced mRNAs. Prediction of many genes and their organization has been...
