3). Consider the four mutations (i-iv) described below: i. One of the mutations causing cystic fibrosis in humans is a deletion of three nucleotides that eliminates a phenylalanine at position 508 of the CFTR protein (D508). Normally, CFTR protein is localized to the plasma membrane, where it functions as a chloride ion channel. D508 CFTR is misfolded and all of it is degraded without ever reaching the cell surface. ii. The yeast transcription factor Gal4p contains a DNA-binding domain and a transcriptional activation domain. An allele with a deletion the gene portion encoding the activation domain encodes a truncated Gal4p containing only the DNA-binding domain. It binds to Gal4p target genes at appropriate binding sites in their upstream regulatory regions, but does not activate their transcription. In cells with both wild type and mutant forms of Gal4p, the truncated Gal4p binds more efficiently to target DNA sequences than wild type. iii. Mutations in the acid maltase gene in…
