Summary Introduction
To determine: The reason due to which mouse did not show lung congestion symptoms of cystic fibrosis.
Introduction: Cystic fibrosis (CF) is an autosomal recessive disease. The disease condition would appear only when an individual has a homozygous recessive (aa) gene for this disorder. This condition causes respiratory tract problems in case of human beings.

Mutations in both copies of the CFTR gene causes cystic fibrosis. Imagine that you have sweat gland samples from several Cystic Fibrosis patients (A-C) with unknown mutations in CFTR. You also have normal (+) sweat gland sample to use as a positive control. А В С А В С Choose which mutation would explain the RNA and protein results in A, B, & C: 1. Promoter/Regulatory mutation 2.

- A wild-type mouse that is heterozygous for two immunoglobulin heavy chain alleles (IgHa/b) generates the population of B cells shown on the left of the figure below. A mouse strain, also IgHa/b, carries an inactivating mutation in the VpreB gene. In addition to producing fewer mature B cells than the wild-type mice, the VpreB-deficient mice generate B cells as shown on the right. What is the explanation of the difference seen between the wild-type and the VpreB-mutant B cells?arrow_forwardDraw a diagram of how we can treatment the Sickle cell anemia by using gene therapy?

- What does the acronym TPA stand for and how is TPA used in diagnostic medicine? Explain briefly.arrow_forwardA research group is studying a bacterium X that binds to mucosal cells in the lung and invades. Wildtype X has an LD50 value of 10 bacteria when administered to mice by inhalation. Using transposon mutagenesis, the researchers have isolated two mutants of X that they call Xmut1 and Xmut2, both of which have LD50 values of 105 when inhaled by mice. However, in tissue culture cells, Xmut1 can invade the cells just as well as wild-type X, while Xmut2 cannot. Provide a possible explanation for these results.arrow_forwardmin+ = confers resistance to minocycline cep+ = confers resistance to cephalexin van+ = confers resistance to vancomycin The following table shows the results of your experiments. Transformation of the recipient cells was conducted, using the DNA of the donor cells. You next selected for recipient cells that had undergone transformation by plating the transformed cells on media containing minocycline. This enabled you to select for min+ cells. The min+ cells were then replica plated onto media containing cephalexin or vancomycin in order to determine the antibiotic resistance phenotypes with respect to these other two antibiotics Questions a) Of the three potential orders of these genes, which orders are possible and which are impossible based on your knowledge of the relative distance? b) Finally, determine the correct order of the three genes. Please include a DIAGRAM to illustrate how you deduced the correct gene order, as well as an explanation of your reasoning.arrow_forward
