Cystic fibrosis is genetic disease caused by mutations in the CFTR gene. The consequence of this is production of an abnormal transmembrane protein that is responsible for producing sweat, mucus, and digestive fluids. Explain in depth the correlation between the defective gene and the abnormal protein that is produced. Be sure to mention the process involved in protein production, whether or not those process(s) have occurred, and their end products.

If an extra nucleotide is inserted in the first exon of the beta globin gene, what effect will it have on the amino acid sequence of the globin polypeptides? Will the globin most likely be fully functional, partly functional, or nonfunctional? Why?
In eukaryotic cells, secreted proteins are initially directed to the endoplasmic reticulum and then via the Golgi, where they are released into the extracellular environment through secretory vesicles. A more easier way would be for secretory protein-producing ribosomes to be localised to a translocon in the plasma membrane, with the protein being secreted directly during translation. Consider three possible benefits of the more roundabout method for protein secretion versus the simpler, more straightforward approach indicated.
As we focused on the translation of mRNA into proteins as well as on protein structure and function. Along the way, we found many opportunities to consider the methods and reasoning by which much of this informationwas acquired. From the explanations given in the chapter,what answers would you propose to the following fundamentalquestion How do we know, based on studies of Neurospora nutritionalmutations, that one gene specifies one enzyme?
Suppose the DNA sequence of a gene with 5 exons contains a mutation at the 5’ end of intron 2. Explain, in 4-8 sentences, the potential effects of this mutation on both the mature mRNA transcript, and the resulting protein. Please help explain this in 8 sentences or less, thank you!
Given the following mRNA sequence, write the peptide sequence that will result from protein translation. Please indicate the correct directionality.
How is it possible that a given mRNA in a cell is found throughout the cytoplasm but the protein that it encodes is only found in a few specific regions of the cytoplasm? Cite a few different possibilities.
Lactose permease, a protein of E. coli, is composed of a single polypeptide that is 417 amino acids in length. By convention, the amino acids within a polypeptide are numbered from the aminoterminus to the carboxyl-terminus. Are the following questions about lactose permease true or false? A. Because the 64th amino acid is glycine and the 68th amino acid is aspartic acid, the codon for glycine, 64, is closer to the 3′ end of the mRNA than the codon for aspartic acid, 68. B. The mRNA that encodes lactose permease must be greater than 1241 nucleotides in length.
