You are studying a mutation in mice, which acts dominantly. Mice that have only one copy of the allele carrying this mutation have a kinky tail phenotype. You identify the gene that the mutation affects and find that the codon that encodes the second amino acid in the predicted protein has been mutated to a stop codon. Would you characterize this mutation as a loss-of-function or a gain-of-function and what specific subtype (hypermorphic, antimorphic, etc. ) within these categories? Explain your reasoning.”
Cystic Fibrosis is a genetically heritable disease caused by the loss of the chloride channel, CFTR. Studies of this gene have found that the Gene includes 250,000bp in the DNA. Scientists found that the mRNA had 6,500 nucleotides, and the final protein had 1480 amino acids.
How much of the mRNA is untranslated?
How much of the RNA that is produced does not leave the nucleus?
One of the mutations that results in a disease phenotype can be easily identified because the mutation results in a much longer mRNA then normal. Where would you look for this mutation? What might this mutation have affected?
Proteins A,B,C, and D in the diagram are encoded by different genes and interact
with each other. Imagine that a mutation in the gene for protein A changes one of the
charged amino acid in the red circle area from positive to negative charge (blue
arrow). this mutation results in a mutant phenotype. Assume a mutation in the gene
for protein B occurs and the double mutants have a phenotype that is almost wild
type. How would you best describe the mutation in gene B?

The gene has one intron that is 450 nucleotides long. After this intron is removed from the pre-mRNA, the mRNA transcript is 1100 nucleotides in length. Diploid somatic cells have two copies of this gene. Predict the size and amount of mRNA from the cytosol of skin cells, which were obtained from the following individuals: • Individual 1: Normal individual with no mutations in this gene. • Individual 2: Homozygous for a deletion that removes the -10 to -100 region of the gene that encodes this mRNA. • Individual 3: Heterozygous in which one gene is normal and the other gene has a deletion that removes the -10 to -100 region. • Individual 4: Homozygous for a five-nucleotide deletion in the intron that removes the GT sequence at the 5' splice site.
