A cross between two Igf Igf- mice is expected to produce which of the following offspring?
O 1 normal:1 dwarf
O All normal
All dwarf
O 3 normal :1 dwarf
Mutation in the fibroblast growth factor receptor (FGFR) gene results in achondroplasia (dwarfism), which is a dominant condition caused by a single base substitution (GGG>AGG) that changes the amino acid glycine at position 480 to arginine (G480R) in the FGFR protein. FGFR is normally active when FGF binds to it, but the mutant FGFR is always on to stimulate signaling that inhibits excessive bone growth.
How can gene therapy be used to treat achondroplasia? Select all that apply.
RNAi that knocks down the mutant FGFR expression
Adeno-associated viral (AAV) vector that carries the wild-type FGFR
Retroviral vector that carries the wild-type FGFR
CRISPR with the wild-type FGFR donor DNA
Using molecular cloning, a hybrid receptoer is produced that consists of the extracellular domain of the B-adrenergic
receptor (B-AR) and the transmembrane and intracellular domains of the EGF receptor (EGFR).
Question:
What is the stoichiometric ratio of epinephrine to the hybrid receptor (B-AR-EGFR)?

- Which arrestin is required for activation of phosphorylation of MDM2 during chronic Iso stimulation? use the following Figures 1and 2 respectively to explain pleasearrow_forwardTroponin is a complex composed of Troponin C (TnC), Troponin I (TnI), and Troponin T (TnT); the complex is found in skeletal and cardiac muscle, but not smooth muscle. Two "isoforms" of TnI and two "isoforms" of TnT are expressed in human skeletal muscle tissue. Q:The isoforms of TnI in the sentence above mean: A:One single TnI gene encodes two different TnI proteins as a result of alternative splicing of the TnI pre-mRNA. B:There are two different TnI genes, each produces a TnI protein.arrow_forwardWhich of the following would you expect to happen if amino acids 579 to 582 (YIYV) in the PDGF-Beta receptor were exchanged with amino acids 992 to 995 (YLIP) from the EGF receptor to give PDGF (YLIP) and EGF (YIYV) (Select all that apply)?

- In Figure 6-2, explain how the mutant polypeptide actsas a spoiler and what its net effect on phenotype is.arrow_forwardIt has been found that blood types (ABO) affect the COVID-19 infection rate and the disease severity. Blood type A individuals are more likely to be infected and more likely to suffer from severe disease. Blood type O individuals seem to be less affected. Outline possible reasons for this. Note: So far, no studies have been published to conclusively answer this question, so there are no "wrong" answers here. The point is to come up with some ideas/hypotheses based on your knowledge about the molecular basis of blood types and what the consequences might be in relation to viral infections.arrow_forwardBased on the NCBI Blastp and reciprocal analysis, are there any mutations to suggest that mus musculus is a good model to test the human FGFR3 gene. This is the only model we have to go off of to predict whether a mouse is suitable. I can’t seem to grasp what exactly I’m suppose to look for in these two photos.arrow_forward
- Would there be a synergistic effect between IGF-IR and HER2 inhibitors? Why or why not?arrow_forwardDraw a cell signaling pathway following EGFR activation in host cells with the possible downstream activities. The new covid-19 strain acts on other cells in the body such as the lungs and kidney via ACE2. (we will say that EGFR is a receptor for the new variant).arrow_forwardA snapshot of a portion of the SARS-CoV-2 spike protein bound to the human ACE2 receptor (taken from PDB) is shown below. The spike protein is in orange and the ACE2 receptor is in green. Within the red-circled region are 2 amino acids connected by a dashed line (added by Dr. David). These amino acids are a tyrosine residue from the spike protein and an aspartate residue from the ACE2 receptor. w cozedarrow_forward
- The Wnt planar polarity signaling pathway nor-mally ensures that each wing cell in Drosophila has a sin-gle hair. Overexpression of the Frizzled gene from a heat-shock promoter (hs-Fz) causes multiple hairs to grow frommany cells (Figure Q15–5A). This phenotype is suppressedif hs-Fz is combined with a heterozygous deletion (DshΔ)of the Dishevelled gene (Figure Q15–5B). Do these resultsallow you to order the action of Frizzled and Dishevelledin the signaling pathway? If so, what is the order? Explainyour reasoningarrow_forwardA -------| B-------> Violet A linear switch-regulation pathway of the type shown here controls flower color in a certain species. The wildtype color is violet, but mutants can be either white or purple. Gene products A and B act in the pathway at the positions and in the manner shown (A is inhibitory, B is intensifying). A and B are the products of genes A and B, respectively. What are the expected phenotypes of: (a) A loss-of-function mutation in A? (b) A gain-of-function mutation in A? (c) A loss-of-function mutation in B? (d) A gain-of-function mutation in B?arrow_forwardIs it true human genome contains 518 kinase-encoding genes and 147 phosphataseencoding genes ?arrow_forward
